| Abstract: | Within the perturbative-recombination model, the charge asymmetries in the D* +–D* ?, D* 0–D* 0, and D + s –D ? s yields are estimated under the kinematical conditions of the COMPASS experiment. Corrections that arise owing to the mass of a light quark in a charmed meson are taken into account. The yield of D + s meaons is predicted to be large in relation to the yield of D ? s mesons. |
