Description
We complete the calculation of the wino-nucleon scattering
cross section up to the next-to-leading order in α_s. As a result, the
uncertainties coming from the perturbative QCD are significantly
reduced to be smaller than those from the nucleon matrix elements. The
resultant scattering cross section is found to be larger than the
leading-order one by about 70%, which is well above the neutrino
background.
