The unbearable lightness of being: CDMS versus XENON
The CDMS-II collaboration has reported 3 events in a Si detector, which are consistent with being nuclear recoils due to scattering of Galactic dark matter particles with a mass of ∼ 8.6 GeV and a cross-section on neutrons of ∼ 2 × 10-41 cm2.

| description | The CDMS-II collaboration has reported 3 events in a Si detector, which are consistent with being nuclear recoils due to scattering of Galactic dark matter particles with a mass of ∼ 8.6 GeV and a cross-section on neutrons of ∼ 2 × 10-41 cm2. While a previous result from the XENON10 experiment has supposedly ruled out such particles as dark matter, we find by reanalysing the XENON10 data that this is not the case. Some tension remains however with the upper limit placed by the XENON100 experiment, independently of astrophysical uncertainties concerning the Galactic dark matter distribution. We explore possible ways of ameliorating this tension by altering the properties of dark matter interactions. Nevertheless, even with standard couplings, light dark matter is consistent with both CDMS and XENON10/100. © 2013 IOP Publishing Ltd and Sissa Medialab srl. |
