| 英文摘要 | QCD corrections to the penguin induced charmless inclusive B decays are performed to an improved leading-log approximation. For process b --> sq(q) over bar (q = uds) and --> , four previous missed 4-quark operators are included to make a complete leading log QCD corrected result. Furthermore, part of the next-leading log effect was also given for the above processes and process b --> sg. In comparison to previous QCD corrected calculations by Grigjanis et al., the inclusive decay rates for process b --> sq(q) over bar (q = ud), b --> ss(s) over bar and --> are suppressed 10%, 14% and 18% respectively. The branching ratio of process b --> sg is enhanced by 2-3 orders, the result for this process is in agreement with the result of Ciuchini et al. |
