Last results and Perspectives of the OSQAR Photon Regeneration Experiment — •Matthias Schott — CERN, Geneva, Switzerland
Recent intensive theoretical and experimental studies shed light on possible new physics beyond the standard model of particle physics, which can be probed with sub-eV energy experiments. The OSQAR photon regeneration experiment looks for the conversion of photon to axion (or Axion Like Particle) using spare superconducting dipole magnets of the Large Hadron Collider (LHC). In this talk we report on first results obtained from a light beam propagating in vacuum within the 9 T field of a single LHC dipole. No excess of events above the background was detected and the two-photon couplings of possible new scalar and pseudo-scalar particles can be constrained to be less than 3.9·10−7 GeV−1 and 4.1·10−7· GeV−1 respectively, in the limit of massless particles. The short and long term perspectives of the OSQAR photon regeneration experiment are also briefly presented.
