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. 


PhysTeV 2019 Les Houches

lh2019 logoThis series of workshops, started 20 years ago, aims  to bring together theorists and experimentalists working on the phenomenology of  TeV colliders with an emphasis on the physics at the LHC. The highlight of the 2019 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. In the light of the LHC results, a reflection on the strategy in HEP and prospects from future facilities (at high and low energy) should be conducted. The Workshop will address issues such as how to best exploit these data as well as how to prepare for future LHC data, and what is most desirable in LHC upgrades. 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 role of machine learning and artificial intelligence will be part of these new development. The Workshop 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: 10-19 June 2019 with emphasis on SM-related issues.

Session II: 19-28 June 2019   with emphasis on New-Physics searches

Johannes Henn, Director and Scientific Member of the Max Planck Institute for Physics


Johannes Henn former Erasmus master student in physics at the Université de Savoie and former PhD student at LAPTh under the supervision of Prof. Emeri Sokatchev, has been appointed as a new Director at the Max Planck Institute for Physics. Johannes, 37 years old, is one of the world's leading experts in the research field of scattering amplitudes, which are used for the precise description of accelerator experiments. It is a very innovative research area, which establishes a close link between theoretical and experimental particle physics. Johannes has been running a research group for theoretical and mathematical physics at Mainz University since 2015.

Another blow for the dark matter interpretation of the Galactic Center Excess


For almost ten years, astronomers have been studying a mysterious diffuse radiation coming from the center of our Galaxy. Originally, it was thought that this radiation could originate from the elusive dark matter particles that many researchers are hoping to find. However, physicists from the University of Amsterdam and the Laboratoire d'Annecy-le-Vieux de Physique Théorique have now found further evidence that rapidly spinning neutron stars are a much more likely source for this radiation.

Recent Advances in Quantum Integrable Systems

These international meetings aim at bringing in contact people working on various aspects of the Theory of Quantum Integrable Systems. Applications of Integrable Systems, such as string/gauge theories, condensed matter physics or statistical physics are also emphasized. In particular, the two last days of RAQIS'18 will be dedicated to a Statistical Physics session devoted to out-of-equilibrium problems.


The conference will be held at LAPTh, Annecy from 10th to September 14th, 2018.

Lauréat prix Daniel Guinier 2017


Le prix Daniel Guinier 2017 de la SFP a été décerné à Vivian Poulin, pour sa thèse intitulée "Signatures gravitationelles et électromagnétiques de particules massives en Cosmologie". Thèse dirigée par Pasquale D. Serpico (CNRS) et codirigée par Julien Lesgourgues (RWTH Aachen).

Vivian Poulin a préparé sa thèse au sein du Laboratoire d'Annecy-le-Vieux de Physique Théorique et de l'École doctorale de physique de Grenoble en cotutelle avec l'Université RWTH d'Aachen.

Ce prix Jeunes Chercheurs/euses de la Société Française de Physique, présenté par la Division Champs et Particules récompense un/e jeune ayant récemment soutenu sa thèse.

L'ensemble du laboratoire le félicite.


Lauréat du prix de Thèse 2018 de la COMUE UGA

 prix-these-uga-2018 vp


Vivian POULIN est l'un des 7 lauréats et lauréates du Prix de thèse 2018 de la Communauté Université Grenoble Alpes. Les travaux récompensés se distinguent par leur excellence et les progrès qu’ils représentent pour la connaissance. Vivian a effectué sa thèse en co-tutelle entre le Laboratoire d’Annecy-le-Vieux de Physique Théorique (LAPTh) et l'Université RWTH d’Aix-la-Chapelle sur les "signatures gravitationnelles et électromagnétiques de particules massives en Cosmologie". L'enjeu de son travail de thèse a été de développer des méthodes pour révéler la nature de la matière noire à travers son influence sur les observables cosmologiques existantes. Le prix sera décerné mardi 26 juin 2018 à Saint-Martin-d'Hères.

The 14th international workshop on the "Dark Side of the Universe 2018" will be held at LAPTh, Annecy, France. The Dark Side of the Universe (DSU) workshops bring together a wide range of theorists and experimentalists to discuss ideas on models of the dark side, and relate them to current and future experiments.

Topics covered include dark matter, dark energy, cosmic rays, cosmology,  gravitational waves, and physics beyond the standard model.
