Abstract |
The authors report limits on annual modulation of the low-energy event rate from the Cryogenic Dark Matter Search (CDMS II) experiment at the Soudan Underground Laboratory. Such a modulation could be produced by interactions from Weakly Interacting Massive Particles (WIMPs) with masses approximately 10 GeV/c(sub 2). They find no evidence for annual modulation in the event rate of veto-anticoincident single-detector interactions consistent with nuclear recoils, and constrain the magnitude of any modulation to <0.06 event (keVnr kg day)(sub -1) in the 5 11.9 keVnr energy range at the 99% condence level. These results disfavor an explanation for the reported modulation in the 1.2-3.2 keV(sup ee) energy range in CoGeNT in terms of nuclear recoils resulting from elastic scattering of WIMPs at >98% condence. For events consistent with electron recoils, no signicant modulation is observed for either single- or multiple-detector interactions in the 3.0-7.4 keV(sup ee) range. |
