Diffractive D_s production in charged current DIS

Abstract

We present a perturbative QCD calculation of diffractive $D_s$ production in charged current deep inelastic scattering. In the two-gluon exchange model, we analyze the diffractive process $\nu N\to {\mu }^{-}N\text{Ds}$, which may provide useful information for the gluon structure of nucleons and the diffraction mechanism in QCD. The cross section of diffractive $D_s$ production with $\text{xBj}=0.005$-0.05 and $E_{\nu }=50$ Gev is found to be $2.7\times 10^{-5}$ pb. In spite of this small cross section, the high luminosity available at the $\nu$-Factory in the future would lead to a sizable number of diffraction events.
