LAPTh, an overview
LAPTh 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:
The UGA Idex project pre-selected
Université de l’innovation
An important hurdle has been crossed on the way to achieve the goal of establishing the UGA, Université Grenoble Alpes, as a world class research and innovation university. The UGA is a conglomerate of universities and research institutions with a multi-disciplinary training programme in Grenoble and in the Alps region. The Frenchh Ministry of Education and Research has announced that the Idex (Excellence Initiative) pre-project of UGA is one out of three pre-projects that has been selected among 7 other applications. This paves the way to the submission of the full project which will be reviewed by an international panel whose results will be made public in January 2016. In case of success this dates will mark a new beginning for the new institution and will be a major boon for all the laboratories involved. For LAPTh this will reinforce our contribution to the Excellence Laboratory Initiative (Labex) Enigmass and build upon our efforts in building a strong collaboration with the Grenoble laboratories.
More details on the UGA Idex project can be found here (in French).
The project stands on excellent scientific foundations. For example, 1 out of 5 inhabitants in the Grenoble Alpes region are, in one way or the other, involved with research and innovation, see this short clip .
PhysTeV Les Houches 2015
In 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 is now 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 propoer 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:
Session I: 1-10 June 2015with emphasis on SM-related issues
Session II: 10-19 June 2015 with emphasis on New-Physics searches
A course on Nonequilibrium Processes
Kirone Mallick from the Institut de Physique Théorique (IPhT) CEA Saclay is giving a set of lectures describing recent advances in systems far from equilibrium. After a review of equilibrium thermodynamics, the lectures will introduce the fascinating identities of Jarzinski and Crooks which quantify the transient violations of the second principle. This will be followed by the fluctuation theorem of Gallavoti-Cohen. Here is the exciting programme
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 extermely small, the standard predicted amount of lithium is off by about a factor 3 larger. 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, Pasquale D. Serpico and Vivian Poulin (LAPTh, CNRS) have shown that a loophole in the calculation of electromagnetic cascades re-opens the possibility of finding an easy way out to the old problem of the lithium abundance.
A course on cosmology by Wessel Valkenburg
Starting 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 Introduction to Cosmology cover
The (6) videos of the lectures can be found on the LAPTh Youtube Channel
A new logo is born !
LAPTh has now a new logo! Putting 5 letters in a square was no easy job. Among a hundred of designs and a lot of discussions in the LAPTh patio, restaurant, sometimes heated but always jovial, this was the final choice. The logo comes now in a couple of versions.

Anonio Pich Lectures : Naturalness and LHC Run 2
As part of the ENIGMASS lecture series, Antonio Pich (University of Valencia, Spain) delivered a series of lectures on 12/13 November (2014) entitled " Probing Naturalness and Electroweak Symmetry Breaking at LHC run-2. Three lectures of 1h30 each were given, each lecture was followed by a debate and exchange with the audience. The target audience were staff physicists, post-docs and PhD students. For more details about the events see here.
