  Recently the CDMS collaboration has reported an excess of events in the
signal region of a search for dark matter scattering with Silicon nuclei. Three
events on an expected background of 0.4 have a significance of about 2 sigma,
and it is premature to conclude that this is a signal of dark matter.
Nonetheless, it is important to examine the space of particle theories capable
of explaining this excess, to see what theories are capable of explaining it,
and how one might exclude it or find corroborating evidence in other channels.
We examine a simplified model containing a scalar mediator particle, and find
regions consistent with the CDMS observations. Bounds from colliders put
important restrictions on the theory, but viable points, including points
leading to the observed thermal relic density, survive.
