Description

The last results and near future plans of the OSQAR experiment at the low energy frontier, i.e. sub-eV range, will be presented. The OSQAR-LSW experiment dedicated to axion like particle search from Light Shining through Wall have been run in 2014 with an unprecedented sensitivity using two spare LHC dipole. The number of incident photons as well as the photon detection efficiency has been increased by using an 18.5 W DC laser and a state-of-the art CCD, respectively. Moreover a new statistical data analysis has been developed. All these improvements have led to new exclusion limits for the di-photon couplings for both scalar and pseudo-scalar particles. The OSQAR-CHASE experiment will look for chameleons, i.e. particles with environment-dependent mass, from the search of a magnetic afterglow effect due to the possible coupling of chameleons to photons. Simulation results from the preparatory phase as well as preliminary data will be presented.
