We report results from the Cryogenic Dark Matter Search at the Soudan Underground Laboratory (CDMS II) featuring the full complement of 30 detectors. A blind analysis of data taken between October 2006 and July 2007 sets an upper limit on the weakly interacting massive particle (WIMP) nucleon spin-independent cross section of 6.6×10[superscript -44] cm[superscript 2] (4.6×10[superscript -44] cm[superscript 2] when combined with previous CDMS II data) at the 90% confidence level for a WIMP mass of 60 GeV/c[superscript 2]. This achieves the best sensitivity for dark matter WIMPs with masses above 44 GeV/c[superscript 2], and significantly restricts the parameter space for some favored supersymmetric models.
