Constraining WIMP magnetic moment from CDMS II experiment

We consider a degenerate or a nearly degenerate dark matter sector where a sizable magnetic moment of a (almost) Dirac type neutral dark matter candidate N is anticipated. Then, due to soft photon exchange, the cross-section in direct detection of N can be enhanced at low Q(2) region. We discuss the implication of this type of models in view of the recent CDMS II report. (C) 2010 Elsevier BM. All rights reserved.
