LAPTh is a mixed research unit (UMR) of the Centre National de la Recherche Scientifique (CNRS) and the Université Savoie Mont Blanc (USMB). labo people003This UMR strucure means, among other things, that it is funded both by the CNRS where LAPTh is part of the National Institute of Physics (INP) and the USMB. Among the  permanent members of the laboratory 18 are CNRS personnel and 8 are faculty staff of the USMB. Post-doctoral fellows are funded through a variety of grants, in particular by Agence National de la Recherche (ANR) grants and European  grants. LAPTh members supervise students at the Masters 2 and PhD level and take part and organise courses at various levels at the Université Savoie Mont Blanc, Université Grenoble-Alpes and in Lyon.

Research: The scientific areas are represented by three broad activities grouped into three teams:

  • Particle physics
  • Particle astrophysics and cosmology
  • Mathematical physics in the team Fields, Strings and Symmetries.higgs pot


In particle physics the team is known for important contributions in both the standard model (electroweak and QCD: from photon to Higgs physics, precision loop calculations, quark gluon plasma) and beyond the standard model (supersymmetry and Higgless scenarios, dark matter).

In cosmology there is leading expertise in the extraction of the cosmological parameters (including data on massive neutrinos), CMBPol and constraints on inflation, and non-standard cosmology.

In mathematical physics one of the most recent breakthroughs was achieved by logo lapth eqts 2members of LAPTh. This concerns the discovery of a dual superconformal in N=4 super Yang-Mills and its connection with Wilson loops. Existence of an underlying Yangian in such systems brought another expertise of LAPTh, integrable systems, to the frontline. Connections to statiscal physics and theoretical biophysics are also developed.



LAPTh is also known for the development of tools for colliders, in astrophysics and in cosmology (micrOMEGAs, DM@NLO, SloopS, Golem, Diphox, USINE, CLASS). LAPTh physicists were among the first, in the subject of dark matter, to underline the synergy between searches at colliders and 'in the sky".

The laboratory benefits from the geographical vicinity of CERN (50kms) and from sharing a building with LAPP initiating with the latter an International Centre for High Energy Physics and Astrophysics (CIPHEA) that has attracted many first class physicists. LAPTh has also been running some world renowned events among them RAQIS in mathematical physics, PhysTeV in particle physics since 1999, the latter having set standards and accords for the physics at the LHC (Les Houches Accords). LAPTh has been awarded an A+ label by the AERES in recognition for the quality of its research. To further illustrate the excellence of LAPTh, it should be mentioned that the laboratory hosts 4 "médailles du CNRS". 6 of our faculty physicists have been nomiated at the Institut Universitaire de France (IUF), they represent more than half of the IUF contingent of the Université de Savoie. Moreover one member of LAPTh is the recipient of two prestigious prizes: Max-Planck and Heineman prize. Very recently one of young researchers received the Alfredo di Braccio Prize of the Accademia Nazionale dei Lincei.

Training: For the period 2005-2009, 21 doctoral students graduated after having pursued their PhD at LAPTh. labo people007As testimony of the attraction of LAPTh 1/3 of these came from the Master Program of Lyon and Grenoble in which LAPTh is involved. For the rest, we have been able to reach out for other students in France (including Grandes Ecoles) and particularly from abroad. The latter have been financed through foreign, binational or Marie Curie fellowships, thanks to vigorous actions outside France. Among these, let us mention that LAPTh has led the proposal of the now successful Erasmus Mundus Joint Doctorate Programme "International Relativity and Astrophysics". In Algeria, we have helped set up and take part into the 3ème cycle de l'Université de Jijel. A member of LAPTh is head of the LIA FVPPL (CNRS-Vietnam Academy of Science and Technology). Many of the students (Master and PhD) in France are a result of his action. Thanks to close scientific collaborations between LAPTh physicists and Università di Torino and Università Roma Tre, six students prepared a «co-tutelle» thesis. Physicists also teach at various doctoral schools in France, Belgium, Germany and Switzerland, organize or teach at summer schools.

AERES assessment: grade A+, in its 2010 report the AERES underlines:

arrowThe excellence of the laboratory: "LAPTh is one of the best French laboratories of theoretical physics, at the forefront on the international scene in all its three main areas of activity: particle physics, mathematical physics, and astrophysics/cosmology. The scientific production is regular and very well-balanced across the fields."

arrowThe multidisciplinary: "LAPTh has a rare mix of first-rate expertise in both the formal and the phenomenological aspects of fundamental physics, ranging from string theory and the search for new physics in accelerator experiments, to astrophysics and cosmology."

arrowThe international involvement, collaboration and attraction: "All three teams are well-inserted in the broader European research landscape, as evidenced by collaborations, participation in networks, invitations to (and organization of) conferences or workshops, and their ability to attract first-rate students and postdocs. The coexistence and good relations with LAPP, and the proximity of CERN, offer many opportunities which are being well exploited."

arrowImportant link with education and public outreach: "The laboratory has a unique program of outreach activities, addressed both to the wider public and to local high-schools. These help the integration of LAPTh in the region, and augment the visibility of fundamental science in a broader sense
