LAPTh, an overview

LAPTh is a mixed research unit (UMR 5108) of the CNRS lapth-lapp(within the Institute of Physics, INP) and the Université de Savoie. It is  located in Annecy-le-Vieux, 5km from the centre of Annecy and about 40km from CERN and Geneva.  The activities of LAPTh are centred around three main areas of research:

  • phenomenology of particle physics,
  • astroparticles and cosmology,
  • mathematical physics in particular field and string theory and  aspects of symmetry. 


Pierre Salati in Pour la Science (Scientific American)


 The issue 426 (April 2013) of the magazine Pour la Science, the French edition of Scientific American, is devoted to a lengthy article on dark stars. It is written by Katherine Freese (University of Michigan, USA), Paolo Gondolo (University of Utah, USA) and our colleague Pierre Salati.

Several measurements in astrophysics and cosmology indicate the presence of a new type of matter, dark matter. Dark matter represents no less than 85% of the matter content of the Universe. The most plausible hypothesis is that dark matter consists of new, electrically neutral and weakly interacting particles.

Many theories describing physics beyond the standard model of particle physics incorporate dark matter candidates. Dark stars, that are,  oddly enough, brighter than a thousand suns, draw their energy from the annihilation of these dark matter candidates.

Les Houches 2013

logo phystev

The next session of the PhysTeV Workshop initiated by LAPTh physicists in 1999 and organized every two years since then, will take place in Les Houches as usual from 3-21 June 2013. This series of workshops has contributed much to the physics of the LHC by bringing together in an a relatively secluded place theorists and experimentalists working either towards a better precision for the standard model observables or on new models and theories for the New Physics. This has led, among other things, to the many celebrated Les Houches Accords and Les Houches Recommendations. 2013 will be the year where we will finally discuss the impact of the newly discovered resonance, which is probably the long sought after LH, …oups Le Higgs.
