About forty five people work at the LPTENS. Our research encompasses many areas in theoretical physics. We on the one hand study the quantization of gravity, mainly in the context of string theory, problems in high energy physics (in particular related to the experiments at the LHC collider at CERN), and questions in observational cosmology rooted in recent data. Our second emphasis covers numerous statistical physics problems connected to disordered systems, solid state physics, computer science, complex systems, and biology, often subjecting experimental data to analytical or numerical treatment. Common tools to both fields are the quantum field theory of particles or extended objects, supersymmetry, and the theory of classical or quantum totally integrable or scale invariant systems.
A NEW PARTICLE has been discovered with 99,9999% confidence level at CERN by the collaborations ATLAS and CMS at the LHC. It has the characteristics of the famous HIGGS BOSON whose hunt has long been one of the top priorities for particle physics.
