| 英文摘要 | In this paper, we calculate the total decay widths for the W+-boson decays, W+ -> B-c + b + (s) over bar + X and W+ -> B-c* + b + (s) over bar + X, up to next-to-leading order (NLO) accuracy within the framework of the nonrelativistic QCD theory. Both the fixed-order and the fragmentation approaches are adopted to do the calculation. Differential decay widths d Gamma/dz and d Gamma/ds(1) are also given. We find that the NLO corrections are significant in those two W+ decay channels. Our numerical results show that at the LHC, there are about 7.03 x 10(4) B-c-meson events and 5.10 x 10(4) B-c*-meson events to be produced via the W+-boson decays per operation year. |
