Luis González-Mestres

From Wikipedia, the free encyclopedia

(Lluís) Luis González-Mestres is a Catalan (Spanish) particle physicist in Annecy and Paris, France. He researches theoretical and experimental particle physics, with particular emphasis on cross-disciplinary research close to astrophysics (e.g. neutrino physics, dark matter, cryogenic detectors, relativity...).

[edit] Birth and education

(Lluís) Luis González-Mestres was born in Barcelona, Spain on 14 March 1948, to Lluís González González and Pilar Mestres Gutiérrez de Pando. His father, a republican, was forced to leave Spain after the fall of Barcelona during the civil war. Although he was later allowed to return to Spain, he still had to face several problems due to his republican past [1] .

Gonzalez-Mestres got his master's degree in Barcelona, and a Diplôme d'Etudes Approfondies (DEA) in France (Orsay). He published his first scientific paper (on dual models) in the spring 1970,[2] being a DEA student.[3] He is a researcher at the Centre National de la Recherche Scientifique (French National Centre for Scientific Research), CNRS, since 1972 and a Docteur d'Etat ès Sciences since 1975. He was a CERN fellow in 1978 and 1979.

[edit] Research and related activities

[edit] Strong interaction Physics

Together with Patrick Aurenche, he opposed f-Pomeron identity patterns and defended the idea of a gluonic Pomeron different from any promoted f-trajectory.[4] These papers were at the origin of some controversy with strong interaction phenomenologists. But in a note added in proof to his article Baryons in the 1/N expansion published in November 1979 [5], Edward Witten referred to the work by Aurenche and Gonzalez-Mestres as a paper dealing with aspects of the 1/N expansion not discussed in his article.

[edit] Cryogenic detectors, neutrinos, dark matter

In January 1984,[6] together with Denis Perret-Gallix, González-Mestres proposed the use of superheated superconducting granules (SSG) of type I superconductors to detect magnetic monopoles. Both authors worked in 1984-90 to develop a SSG detector for this project, but also for a SSG solar neutrino detector following a proposal by Georges Waysand. In 1985, following a suggestion by Mark Goodman and Edward Witten,[7] they also started considering a SSG dark matter detector [8] . Gonzalez-Mestres gave a lecture on the SSG detectors at the January 1987 Erice School [9] .

Gonzalez-Mestres and Perret-Gallix simultaneously considered alternative detectors for neutrinos and dark matter, such as special scintillators [10][11] . They formulated in 1988 [12] the original proposal of the luminescent bolometer (also called scintillating bolometer) with simultaneous detection of light and heat [13][14], that is now the basic instrument of the CRESST (Dark Matter Search) experiment,[15] of the ROSEBUD experiment [16] and (partially) of the EURECA (Dark Matter Search) project.[17] In 1989, Gonzalez-Mestres and Perret-Gallix further emphasized the potentialities of such a detector for particle identification and background rejection.[18] In 1991-92, Gonzalez-Mestres also discussed the possible use of the luminescent bolometer to improve effective segmentation and energy resolution in solar neutrino experiments incorporating an indium target [19][20] He considered the use of arrays of superconducting tunnel junctions to simultaneously detect light and phonons.

Gonzalez-Mestres and Perret-Gallix plaid an important role in driving the first steps of the international cross-disciplinary exchanges on cryogenic detectors. In particular, they organized in Annecy in 1988 the second european Workshop on Low Temperature Detectors for Neutrinos and Dark Matter [21] . They were invited to present this topic in the CERN Courier, the CERN review for the general public [22], as well as in CNRS Info, the CNRS press newsletter [23] . Gonzalez-Mestres gave rapporteur talks at the 1988 ESO-CERN Symposium [24] and at a parallel session of the 24th International Conference on High-Energy Physics (Munich, August 1988) [25] .

In 1990, together with Alain de Bellefon et Pierre Espigat, Gonzalez-Mestres proposed a cosmion detection experiment using a 100 mg thermal bolometer.[26] A CNRS cross-disciplinary program on dark matter bolometric detection, including Noël Coron and other astronomers, was presented by Gonzalez-Mestres before the Scientific Council of the Laboratoire Souterrain de Modane (LSM) and approuved by French institutions in July 1990. Tests at LSM involved in particular LiF [27] and sapphire [28] thermal bolometers.

[edit] Relativity and Cosmic Rays

González-Mestres is the author of the superbradyon hypothesis he formulated in 1995,[29] conjecturing the existence of a class of particles with positive mass and energy, but with a critical speed in vacuum much larger than the speed of light. His works on superluminal particles and Lorentz symmetry violation (LSV) assume the existence of a privileged local inertial frame, called the vacuum rest frame.

He pointed out that the existence of superbradyons would necessarily imply LSV for "ordinary" particles, as well as a different early cosmology and new possibilities for dark matter, inflation and other fundamental issues. According to Gonzalez-Mestres, superbradyons can be the ultimate constituents of matter.

In June 1996, González-Mestres suggested [30] that spontaneous decays of superbradyons could be at the origin of cosmic rays with energies above the Greisen-Zatsepin-Kuzmin limit (GZK cutoff). In May 2009,[31] he has claimed that superbradyon spontaneous decays and similar interactions can be candidates to explain data on electron and positron abundances (PAMELA, ATIC, Fermi LAT, HESS, PPB-BETS) considered as possible dark matter signatures. After his June 1996 paper, the idea that different critical speeds in vacuum woul lead to decays in the high-energy cosmic-ray region was also used by Sidney Coleman and Sheldon Glashow in 1997 in a more conventional scheme [32] . The April 1997 version of this paper refers to the work by Gonzalez-Mestres. Other authors also started considering ultra-high energy cosmic-ray (UHECR) production by the decay of various possible heavy objects.

In April 1997, postulating the existence of a vacuum rest frame and a quadratic momentum dependence for the effective LSV parameters, González-Mestres pointed out [33] that Lorentz symmetry violation for "ordinary" particles can naturally lead to a suppression of the GZK cutoff and that, under the same hypothesis, unstable particles can become stable at ultra-high energy. More generally, the stability and decays of ultra-high energy particles would depend on LSV parameters. This paper has been cited by the CERN Courier [34]. These original ideas were also presented [35] at the 1997 International Cosmic Ray Conference (ICRC) whose copyrighted Proceedings were distributed to the participants before the beginning of the conference in July 1997 [36], and at a pre-conference [Pierre_Auger_Observatory|AUGER] workshop associated to this conference.[37]

1997 and subsequent papers by González-Mestres also predicted the suppression of synchrotron radiation at high energy as a consequence of LSV. His suggestion, and the explicit calculation he published in November 2000,[38] were applied by Jacobson, Liberati and Mattingly [39] to the observation of 100-MeV synchrotron radiation from the Crab nebula (see also [40]).

In 2002, González-Mestres analyzed [41] a previous attempt by David A. Kirzhnits and V.A. Chechin (June 1971) [42][43] to apply LSV to ultra-high energy cosmic-ray physics, and showed that their model does not allow to explain a possible suppression of the GZK cutoff. The failure of the Kirzhnits-Chechin approach, based on an extension of the Lorentz symmetry to Finsler algebras, to reproduce a possible absence of the GZK cutoff is due to the assumption that the laws of Physics be identical in all inertial frames. It also follows from this result that the Kirzhnits-Chechin model was actually the first formulation of current conventional [Doubly_special_relativity|doubly special relativity] (DSR), which does not lead to new physics for ultra-high energy cosmic-ray experiments. To stress the difference between his own approach and the standard DSR developed more recently by other authors, González-Mestres calls the former weak doubly special relativity (WDSR) [44] . These new ideas and results were presented at the I Symposium on European Strategy for Particle Physics [45] . As in the previous papers by Gonzalez-Mestres, a fundamental assumption of WDSR is the existence of a privileged local vacuum rest frame.

The work by Gonzalez-Mestres on superbradyons and LSV has opened a new research field centered around checks of relativity at UHECR energies. His original contribution in this domain has been explicitly evoked by The New York Times.[46] in December 2002.

[edit] Current research

More recent work by González-Mestres concerns the implications of AUGER and HiRes data for patterns of Lorentz symmetry violation,[47] but also superbradyonic dark matter [31] and possible tests of quantum mechanics and energy conservation at ultra-high energy.[48] [49] .

[edit] Other activities

Luis González-Mestres has been a member of the Comité National de la Recherche Scientifique (Section of Theoretical Physics) in 1983-87. He is a well-kown "dissident" scientist. Some of his lawsuits (for instance, against recruitment and promotion procedures [50] or the confidentiality of some reports on CNRS management[51]) successfully questioned the institutional behaviour. Since 2001, he is a candidate to the main CNRS elections and proposes in particular the suppression of the Directeurs de Recherche (Reseach Directors) corps that he considers as deprived of realistic professional grounds. He has also made public statements on the governement policy concerning the reserve duty of French researches in Egypt [52] and introduced legal action against controversial decrees instauring new police and intelligence files [53]. He was a member and a representative of the Intersyndicale (joint local unions) of the Laboratoire de Physique Corpusculaire at Collège de France [54]. His role appears, for instance, in the Intersyndicale communiquees [55] reproduced by alternative medias like La Gauche [56] and used by several conventional newspapers. The Intersyndicale opposed to the policy of research laboratory suppression at Collège de France. The LPC crisis was evoked several times by the French medias [57] and gave rise to a large number of public written questions to the government from French deputies and senators in the period 1997-1999 [58] .

In November 1996, together with other members of the Laboratoire de Physique Corpusculaire (LPC) of Collège de France, Gonzalez-Mestres was an invited participant to the parliamentary audition [59] of Carlo Rubbia's Energy amplifier project by the OPECST (Office Parlementaire d'Evaluation des Choix Scientifiques et Technologiques). Gonzalez-Mestres emitted a critical view concerning the budget asked by Carlo Rubbia as compared to the feasibility statuts. Other LPC members, like Jacques Maillard, questioned the feasibility of the Energy amplifier. The French scientific hierarchy was strongly supporting Rubbias's application, but some industrial branches were skeptical. In June 1998, a cautious report by Deputies Christian Bataille and Robert Galley [60] described Rubbia's project as "médaille d'or du marketing scientifique" (scientific marketing gold medal).

In 1999, together with Michel Deza, González-Mestres was among the founders of the Association Contre le Harcèlement Professionnel (ACHP [61]), one of the first French associations against professional harassment, of which he is the president. In 2000, together with Jacques Gabarro-Arpa, he founded Indépendance des Chercheurs,[62] a collective defending the independence of French research against lobbying and private interests.

Indépendance des Chercheurs is strongly opposed to the current policy of Nicolas Sarkozy and Valérie Pécresse about CNRS, research and universities. The collective denounces a "takeover bid" from corporations [63] and a "managerization" of CNRS,.[64][65] . They also criticize on ethical grounds the role of the so-called "refereed reviews", and question their need in the internet epoch.

Although he is not a member of the French Communist Party, González-Mestres was, as the president of ACHP, a member of the working group that helped this party to prepare his private bill of December 1999 against harassment at work submitted to the Assemblée Nationale.[66]

González-Mestres has also a scientific blog, Science, connaissance et conscience,[67] and a more political one, Notre Siècle.[68] Among the subjects dealt with are the ethics of science since the 19th century and possible scientific frauds in racial theories used to justify Europe's colonial expansion,.[69][70]

[edit] Controversies

An exploration of Arxiv and of all relevant databases clearly shows that the 1997 suggestions by Gonzalez-Mestres concerning the suppression of the GZK cutoff and the stability of unstable particles at ultra-high energy, as a consequence of Lorentz symmetry violation, were prior to equivalent proposals [71] by Sidney Coleman and Sheldon Glashow that do not mention the previous work by González-Mestres. Reacting to this situation, González-Mestres wrote in March 2000 [72] :

"It should be noticed that our description of all these phenomena and, in particular, of points a) and b) , on the grounds of DRK was prior to any similar claim by Coleman and Glashow (...)"

(DRK stands for deformed relativistic kinematics. The points a) and b) refer to the absence of GZK cutoff and to the prediction that "unstable particles with at least two stable particles in the final states of all their decay channels become stable at very high energy".)

At the time, González-Mestres was a well-known member of the LPC Intersyndicale and was meeting some professional difficulties.

In his book The Trouble With Physics, Lee Smolin wrongly attributes to Coleman and Glashow the original idea that LSV could lead to a suppression of the GZK cutoff. About Gonzalez-Mestres, he writes :

"Remarkably, it took until the mid 1990 for us to realize that we could indeed probe the Planck scale. As sometimes happens, a few people recognized it but were in effect shouted out when they tried to publish their ideas. One was the Spanish physicist Luis Gonzalez-Mestres, of the Centre National de la Recherche Scientifique in Paris..."

Although it is true that González-Mestres had to face strong institutional pressure, not only because of his unconventional research subject but also due to the conflicting situation [73][74] of the Laboratoire de Physique Corpusculaire at Collège de France, it is unjustified to state that he was actually prevented from making his work public in due time. The existence of the arXiv electronic archive and of other e-publishing sites, as well as some international conferences abroad, allowed González-Mestres to disseminate his results and ideas. In 1997, Gonzalez-Mestres had been an invited speaker at the AUGER pre-conference Workshop [37] of ICRC 1997 and at the Maryland Worksop "Observing giant cosmic ray air showers from >10E20 eV particles from space".[75] His work was cited in the 2000 review article by M. Nagano and A.A. Watson. [76]

However, for a long period including the year 1997, Gonzalez-Mestres had no funding from CNRS to attend conferences and was forced to pay himself most of the expenses. Furthermore, the organizers of the Fifth International Workshop on topics in Astroparticle and Underground Physics (TAUP 1997, L'Aquila, September 7–11, 1997) refused to include his contribution [77] in the proceedings [78] after it had been accepted and presented at the conference. Gonzalez-Mestres had complained about an invited talk [79] by Glashow at the same workshop that included his original results without mentioning his work. At the time of the workshop, Gonzalez-Mestres had posted to arXiv seven papers concerning the possible suppression of the GZK cutoff, the influence of LSV on the stability and decays of particles and nuclei at high energy and several related items. TAUP 1999 was held at Collège de France.

In a note of February 19, 2010, Gonzalez-Mestres has reacted [80] to the above mentioned assertions of the book The Trouble With Physics attributing to Coleman and Glashow some of his original ideas and stating that he had been prevented from publishing his results.

[edit] Miscellaneous

Gonzalez-Mestres is a master of the International Chess Federation.[81] But, according to his blog,[1] he has not played chess for thirty years. He was the Spain junior champion in 1964 and 1966. In 1965, he participated to the World Junior Chess Championship in Barcelona.

He studied at the University of Barcelona in 1965-69, a period of strong rise of the student movement. After his arrival in France (Orsay) in September 1969, he was one of the founders of the CEDE (Comisiones de Estudiantes Demócratas Españoles), a Spanish student organization based in France and devoted to support the struggle against Franco's regime in the 1970s.

RER B : voyage sur la ligne qui déraille
Le RER B est la deuxième ligne de train la plus chargée d’Europe, et pourtant elle souffre de nombreuses tares : quatre terminus, un tunnel partagé avec le RER D et, surtout, un sous-investissement chronique de la part de la région et de l’État. Les usagers souffrent, les conducteurs aussi.

Étrangers sous OQTF : la justice recadre la préfecture de Seine-Maritime
Le tribunal administratif de Rouen vient de débouter la préfecture qui demandait aux gestionnaires de centres d’hébergement d’urgence d’exclure de leur dispositif « insertion » les étrangers en situation irrégulière faisant l’objet d’une obligation de quitter le territoire exécutoire. Une décision qui vient contredire les circulaires et les récents engagements du ministère de l’intérieur.

La précarité étudiante s’enracine et le gouvernement répond à côté
Le gouvernement vient de débloquer 10 millions d’euros pour soutenir les associations qui agissent en faveur des étudiants précaires. Seulement, les principaux acteurs considèrent que la réponse est insuffisante et attendent des mesures structurelles pour endiguer la pauvreté des étudiants.

À Mykolaïv, les morts hantent civils et militaires
La ville de Mykolaïv subit depuis des mois le manque d’eau potable et les coupures d’électricité. La région a été bombardée sans relâche par l’armée russe jusqu’à la mi-novembre 2022 et plus de la moitié des habitants a quitté les lieux. Civils et militaires restés sur place racontent leur « cauchemar ».

Incendie de forêt : les causes ne sont pas que climatiques
[Rediffusion] Les forêts du Sud en particulier demandent beaucoup d'attention pour ne pas prendre feu. Coupe feu, garde-forestiers, défrichages, surveillances, pompiers de proximité, les moyens sont-ils encore là ou ces incendies sont-ils causés par l'impéritie des pouvoirs publics ?

Des chênes (français) pour la Chine
Fric-frac dans les forêts françaises. Voler du bois n’est pas une mince affaire. Et pourtant, dans les Pyrénées, en Moselle, en Vendée, dans le Nord, le brigandage se multiplie. A l’heure des drones, GPS et autres trackers… (Gilles Fumey)

Reboiser les forêts brûlées est favorisé par une niche fiscale
Si l'investissement forestier offre des possibilités de rendement limitées, il constitue en revanche une niche fiscale qui permet de réduire le montant de son impôt sur le revenu. L'investissement forestier réalisé par une personne domiciliée en France lui permet de bénéficier d'un avantage fiscal, que ce soit au titre de l'impôt sur le revenu ou de l'IFI (impôt sur la fortune immobilière).

Vidéo - le gouvernement empêche les débats sur les forêts publiques par 49-3
Il y a un mois, nous avons publié ici une tribune signée par plus de 40 parlementaires, demandant un débat sur l’avenir de l'Office National des Forêts dans la loi de finances avant le 49-3 du gouvernement. Devinez quoi : les débats devaient avoir lieu le 2 novembre à 17h05. Le 49-3 a été activé le 2 novembre à 17h00. Mais tout n'est pas perdu : la suite se joue au Sénat dès mercredi.
