英文摘要: We study the hadronic production of B(s) and B(s)(*) mesons within the fixed-flavor-number scheme, in which the dominant gluon-gluon fusion mechanism is dealt with by using the complete alpha(4)(s) approach. Main theoretical uncertainties for B(s) and B(s)(*) production at the Tevatron and LHC are presented. It is found that when m(s) increases by steps of 0.1 GeV, the integrated cross section of B(s)((*)) decreases by 80%-100%. When m(b) increases by steps of 0.1 GeV, it changes by similar to 10%, while the uncertainties caused by the parton distribution function and the factorization scale vary within the region of 15 to 13. Considering a possible kinematic cut on the transverse momentum and the rapidity cut for the detectors at the Tevatron and LHC, we also make estimations on the B(s) and B(s)(*) production with various kinematic cuts.
