Abstract
Recently, axionlike particle search has received renewed interest. In particular, several groups have started “light shining through a wall” experiments based on magnetic field and laser both continuous, which is very demanding in terms of detector background. We present here the limits obtained so far with our novel setup consisting of a pulsed magnetic field and a pulsed laser. In particular, we have found that the axionlike particle two photons inverse coupling constant is provided that the particle mass . Our results definitively invalidate the axion interpretation of the original PVLAS optical measurements with a confidence level greater than 99.9%.
