‘Possible Hints’ of Dark Matter from CDMS-II

Last weekend the Cryogenic Dark Matter Search (CDMS-II), located in Minnesota’s Soudan mine and long spearheaded by Bernard Sadoulet of Berkeley Lab’s Physics Division and UC Berkeley, with Stanford’s Blas Cabrera, announced good odds that three events observed in a recent search were not background noise but lightweight particles of dark matter. The events were caught by backstop silicon detectors instead of CDMS-II’s principal detectors, made of more massive germanium, and their unusually low mass conflicts with results of some other experiments and leading theories about dark matter particles, but may be consistent with other results and newer proposals.
