Query: Light Dirac right-handed sneutrino dark matter   We show that mostly right-handed Dirac sneutrino is a viable supersymmetric
light dark matter candidate. While the Dirac sneutrino scattering with nuclei
is dominantly through the $Z$ boson exchange and is stringently constrained by
the invisible decay width of $Z$ boson, it is possible to realize a large
enough cross section with nucleon to account for possible signals observed at
direct dark matter searches such as CDMS II-Si or CoGeNT. Even if the XENON100
limit is taken into account, a small part of signal region for CDMS II-Si
events remains outside the excluded region by XENON100.
