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. 


Group Theory Lectures 2015

Following the success of the course that Paul Sorba gave 2 years ago, our new PhD students and post docs asked Paul to renew the experience. The Group Theory and its Applications course is to be delivered over about 10 sittings.  The course will cover 

1) Elements of group theory and their importance in particle physics

2) Lie groups and Lie algebras

3) Classification of semi-simple Lie algebras

4) Representations of simple Lie algebras

5) Applications: spectroscopy of elementary particles, gauge theory, grand unification models

6) Extensions: superalgebras (for supersymmetry); quantum groups (for integrable systems); exceptional algebras and infinite dimensional algebras (for string theory)

Anonio Pich Lectures : Naturalness and LHC Run 2

higgs pot

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.

In Pour La Science, Supernovae and Neutrinos

pour la science neu serpico opt Pasquale SERPICO contributed to the September 2014 Edition of Scientific American (Pour La Science) that covered a few aspects of the fascinating neutrinos. His contribution explained how the signal from a supernova can be used to infer the pattern of masses of these elusive particles.

Neutrinos (and their antiparticles, antineutrinos) are copiously produced in numerous particle physics processes at different depths in the core of collapsing stars (Supernovae). They also come in three varieties (or flavours), as defined by the process by which they were created.

Raqis 2014


Bringing together about 80 participants, the 6th edition of the international conference RAQIS (Recent Advances in Quantum Integrable Systems) was held from 1 to 5 September 2014 in Dijon (France).

Co-organised by LAPTh and the University of Burgundy, it has become a major event for specialists in quantum integrable systems. Last meeting of the ANR programme 'DIADEMS', the conference was to hear about forty presentations covering the latest developments in the field from mathematical aspects to applications in string theory, statistical physics and condensed matter physics.

LAPTh is a member of HiggsTools, an Initial Training Network (ITN) supported by the 7th Framework Programme of the European Commission.

HiggsTools consists of 10 teams from 37 European Universities and Research Institutes, one International Organisation (CERN), and 4 partners from the private sector.

LAPTh is the coordinator of the French participation. The programme covers the important physics of the Higgs and the concomitant topic of the nature of the electroweak symmetry breaking and what may lie beyond it. More info here.


Fête de la Science 2014


On the occasion of the festival of science, LAPP and LAPTh will open their doors on  Saturday 11 and Sunday 12 October  2014  from 10am to 18pm keeping up with this annual tradition.

We will make you discover more about  the experiments  carried at LAPP as well as the various activities both experimentalists and theorists (of LAPTh) are involved in.  Visitors will meet and interact with  physicists, engineers and technicians through different stands and stalls that represent the many research topics carried in our laboratories: Study of  the Higgs particle, the search for new particles at the LHC , anti-matter , cosmic rays  as well as the role of electronics, computers and mechanics in neutrino experiments, gravitational waves and the search for dark matter.

Dark Matter in the Front Line

francecultureFrance Culture in partnership with  Pour la Science magazine (French edition of Scientific American) invited  Richard Taillet from the LAPTh Astrophysics and Cosmology Team and Professor at Université de Savoie to talk  about Dark Matter Hunting in Underground Experiments. He reviewed the human challenges and the  technological infrastructure that are put in place today in the search of the missing dark matter of the universe. Thanks to more and  more precise instruments installed in old mines, physicists are searching for the elusive dark matter. With detector sensitivity  increasing the noose is tightening around this hypothetical component of the Universe ....

Listen to the radio programme  (Richard talks at 45 minutes into the programme)
