I report recent results and the status of the Cryogenic Dark Matter Search (CDMS II) experiment at the Soudan Underground Laboratory in Minnesota, USA. A blind analysis of data taken by 30 detectors between October 2006 and July 2007 found zero events consistent with WIMPs elastically scattering in our Ge detectors. This resulted in an upper limit on the spin-independent, WIMP-nucleon cross section of 6.6 × 10−44 cm2 (4.6 × 10−44 cm2 when combined with our previous results) at the 90% C.L. for a WIMP of mass 60 GeV/c2. In March 2009 data taking with CDMS II stopped in order to install the first of 5 SuperTowers of detectors for the SuperCDMS Soudan project. Analysis of data taken between August 2007 and March 2009 is ongoing.

- Dark matter and a new gauge boson through kinetic mixing (2010, methodology): “In particular, by using this procedure we fix a combination of ǫ and gX (≃ ǫgX in the limit ǫ ≪ 1) as a function of the two masses mψ and mX. In section 5, the spin-independent DM-nucleon cross section is calculated and compared to the recent CDMS II [ 15 ] and XENON100 [16] results.”
