Description
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, events observed at direct dark matter searches such as CDMS II-Si or CoGeNT can be account for.
