A Realistic Assessment of the Sensitivity of XENON10 and XENON100 to
  Light-Mass WIMPs
  The underlaying assumptions and uncertainties involved in the derivation of
WIMP exclusion limits from XENON10 and XENON100 detectors are examined. In view
of these, recent claims of sensitivity to light-mass Weakly Interacting Massive
Particles (WIMPs) are shown to be overstated. Specifically, bounds constraining
regions of interest in WIMP parameter space from the DAMA/LIBRA, CoGeNT and
CRESST experiments can be assigned a very limited meaning, if any.
