D Meson Production in Neutrino DIS and Polarized Strange Quark Distribution

Semi-inclusive $D / \Dbar$ meson productions in neutrino deep inelastic scattering are studied including ${\cal O}(\alpha_s)$ corrections. Supposing a future neutrino factory, cross sections and spin asymmetries in polarized processes are calculated by using various parametrization models of polarized parton distribution functions. We suggest that $\Dbar$ production is promising to directly extract the strange quark distribution.
