Bayes and present dark matter direct search status
  Recently there has been a huge activity in the dark matter direct detection
field, with the report of an excess from CoGeNT and CRESST along with the
annual modulated signal of DAMA/Libra and the strong exclusion bound from
XENON100. We analyse these results within the framework of Bayesian inference
and evidence. Indeed Bayesian methods are well suited for marginalizing over
experimental systematics and background. We present the results for
spin-independent interaction on nucleus with particular attention to the low
dark matter mass region and the compatibility between experiments. In the same
vein we also investigate the impact of astrophysical uncertainties on the WIMP
preferred parameter space within the class of isotropic dark matter velocity
distributions.
