Hadronic production ofS- andP-wave states of\(\bar b\)-quarkonium-quarkonium

In the leadingO(αs4) order of the perturbative QCD, the hadronic production cross-sections ofS- andP-wave states ofBc 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 intoBc. In the given order, the cross-sections of the hadronic production of theP-wave states are calculated for the first time. Their contribution into theBc 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.
