Charge asymmetry in the photonic production of charmed mesons

Abstract

Charge asymmetries for the charm meson production ($D^{\ast +}$--$D^{\ast -}$, $D^{\ast 0}$--${\bar{D}}^{\ast 0}$ and $D_s^{+}$--${\bar{D}}_s^{-}$) have been estimated for the COMPASS kinematic conditions in the framework of perturbative recombination model. Mass corrections have been taken into account in the calculations. The large asymmetry for $D_s^{+}$--${\bar{D}}_s^{-}$ production has been predicted.
