摘要
We consider the possibility that the recently reported events at the CDMS-II direct dark matter detection experiment are the result of a coherent scattering of supersymmetric neutralinos. In such a scenario we argue that nonuniversal soft supersymmetry breaking gaugino masses are favored with a resulting lightest neutralino with significant Higgsino and wino components. We discuss the accompanying signals which must be seen at liquid-xenon direct detection experiments and indirect detection experiments if such a supersymmetric interpretation is to be maintained. We illustrate the possible consequences for early discovery channels at the LHC via a set of benchmark points designed to give rise to an observed event rate comparable to the reported CDMS-II data.
