  • The PVLAS collaboration has recently reported the observation of a rotation of the polarization plane of light propagating through a transverse static magnetic field. Such an effect can arise from the production of a light, mA ~ meV, pseudoscalar coupled to two photons with coupling strength gA? ~ 5 ? 10?6 GeV?1. Here, we review these experimental findings, discuss how astrophysical and helioscope bounds on this coupling can be evaded, and emphasize some experimental proposals to test the… CONTINUE READING
