- Аннотация: In the leadingO (α s 4 ) order of the perturbative QCD, the hadronic production cross-sections ofS- andP-wave states ofB c meson are calculated. The results for theS-wave levels are compared with the values given in other papers as well as in the model of thebquark fragmentation intoB c . In the given order, the cross-sections of the hadronic production of theP-wave states are calculated for the first time. Their contribution into theB c meson production is less than 10%. There is a strong difference between the predictions of the fragmentation model and the exact perturbative calculations. These differences are discussed in details for the differential distributions over various kinematical quantities.
