WISPs from strings
Dr. Mark Goodsell (CERN)

WISPs, specifically the axion, axion-like particles and hidden photons, are being searched for in a wide variety of experiments (including MAMI) and astrophysical observations. I shall discuss some of their phenomenology, before describing how they can be found in the LARGE volume scenario (or more generally IIB string theory), what can be predicted for their properties, and some remarks about cosmology. For hidden U(1)s, heterotic orbifolds can also yield interesting models and if time permits I shall describe some work on these.
