Diffractive Ds production in charged current DIS

We present a perturbative QCD calculation of diffractive Ds production in charged current deep inelastic scattering. In the two-gluon exchange model, we analyze the diffractive process νN→μ−NDs+, which may provide useful information for the gluon structure of nucleons and the diffraction mechanism in QCD. The cross section of diffractive Ds production with xBj=0.005–0.05 and Eν=50 GeV is found to be 2.7×10−5 pb. In spite of this small cross section, the high luminosity available at the ν-Factory in the future would lead to a sizable number of diffraction events.
