Recent results on the low mass dark matter WIMP controversy: 2011
  We review the confused situation concerning evidence for low-mass WIMPs. In
the past one half year there have been new results concerning the existence of
WIMPs at low mass including the new XENON 100, 100-day data, additional CDMS
results, the publication of annual variation data from LVD and Borexino and new
CoGeNT data. Along with the S2 analyses of the XENON 10 data we provide an
overview of this situation. We discuss new results from 2011 here. We also
discuss the origin of annual variations of signals in underground laboratories.
This article is meant to be an update of recent experimental results. It is not
a critical comparison of the claims of various experimental groups. Such
critiques are made in public conferences and meetings. There is currently an
intense discussion being carried out about the low mass WIMP region with many
different viewpoints. We have little to say about this situation except that
the scientific method usually insures the correct results will eventually
surface.
