Effects of CP violation on event rates in the direct detection of dark matter - art. no. 063505.

A full analytic analysis of the effects of CP violating phases on the event rates in the direct detection of dark matter in the scattering of neutrali nos from nuclear targets is given. The analysis includes CP violating phase s in softly broken supersymmetry in the framework of the minimal supersymme tric standard model when generational mixings are ignored. A numerical anal ysis shows that large CP violating phases including the constraints from th e experimental limits on the neutron and the electron electric dipole momen t can produce substantial effects on the event rates in dark matter detecto rs.
