Description

Cosmology and astrophysics indicate that our Universe contains a considerable amount of `dark matter’ that is associated with an unknown elementary particle. LIPSS experiment at Jefferson Lab used a high average-power laser beam from a Free Electron Laser to probe for two-photon coupling of such particles using a `light shining through a wall’ technique. Non-observation of a new scalar boson signal and kinetic mixing with hypothetical hidden-sector paraphotons provided new constraints on masses and coupling strength of these particles. Plans for future measurements, in particular, for high-sensitivity `chameleon' searches and MeV-GeV scale A'-boson production will be outlined
