Halo-independent analysis of direct detection data for light WIMPs

Understand

We present a halo-independent analysis of direct detection data on "light WIMPs," i.e.

• weakly interacting massive particles with mass close to or below 10 GeV/c^2.
• We include new results from silicon CDMS detectors (bounds and excess events), the latest CoGeNT acceptances, and recent measurements of low sodium quenching factors in NaI crystals.
• We focus on light WIMPs with spin-independent isospin-conserving and isospin-violating interactions with nucleons.
