Solar ~Axions

file PPT - 3,3MB

The direct search for solar axions with CAST and other experiments will be presented. Fundamental solar problems insisting since decades are suggestive for a new scenario. Accumulated observational evidence favours the exciting axions or other objects with similarly exotic properties as the common solution. Then, experiments like CAST, PVLAS, etc. are already at work also elsewhere.

PVLAS and the stars

I discuss the PVLAS results at the light of the astrophysical constraints on axion-like particles. I propose some particle physics models where those constraints are evaded. The connection with CAST will be touched upon.

The BMV project

The BMV (Biréfringence Magnétique du Vide) project is based on very intense pulsed magnetic fields, developed at LNCMP, and a very sensitive optical device to detect the effects induced on a laser beam by such fields. This research activity have been developed in Toulouse, France, by two institutes (LCAR-IRSAMC, LNCMP), in collaboration with the LMA-VIRGO of Lyon, France. Our goal is to assemble a first version of our experience in 2006, and to obtain first results in 2007. We also plan to use our pulsed magnet at the LULI (Laboratoire pour l'Utilisation des Lasers Intenses) in Paris to perform a photon regeneration experiment.
