## LAPTh, an overviewLAPTh is a mixed research unit (UMR 5108) of the CNRS (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.
## News## PhysTeV Les Houches 2015In a few weeks the high energy physics team will be going to Les Houches. We will be overseeing the 9th session of the LH PhysTeV. This session will coincide with the first beams at the LHC which will soon be running at 13TeV. The highlight of the 2015 Les Houches Edition is to take full advantage of the data that has been collected at the LHC so far and prepare for the future runs. The Workshop will devote particular attention to:(i) Higgs physics, and how it shapes our view on the mechanism of electroweak symmetry breaking; (ii) related searches for New Physics and (iii) progress in new techniques for the calculations and simulation of Standard Model processes. These activities will be conducted in close connection with the development and improvements of related theory tools, in particular of Monte-Carlo event generators. The Workshop proper runs over one year, including two meetings in Les Houches in the month of June, and exchanges and collaborations before and after the meetings. The meetings in Les Houches will consist of two sessions:
## A course on Nonequilibrium Processes
1. Review of statistical physics: Equilibrium versus Non-equilibrium. Dynamics, Detailed Balance and Time-reversal. ## A Possible solution to the Lithium problem?Big Bang Nucleosynthesis (BBN) is an admirable achievement of the standard cosmological model as it very precisely predicts the amount of the most abundant elements, in particular hydrogen and helium. On close inspection the picture is marred by a long standing and annoying problem. Though its abundance is extremely small, the standard predicted amount of lithium is about a factor 3 larger than what observed in some metal-poor stars believed to trace the primordial abundance. Tweaking the theory of BBN to correct the lithium abundance affects that of the hydrogen or helium to an extent that this is ruled out by the Cosmic Microwave Background (CMB). In a very recent paper, ## A course on cosmology by Wessel ValkenburgStarting Monday 20 January Wessel Valkenburg (Lorentz Institute, Leiden Univ., NL) will give a series of 5 lectures on cosmology. The lectures require no prior knowledge of the subject and is addressed to both theorists and experimentalists, physics PhD students and researchers alike. The 5 lectures The (6) videos of the lectures can be found on the LAPTh Youtube Channel ## More Articles... |
