在即将运行的LHC实验上可以观测到大量的Bc介子,使得对Bc介子的研究成为可能.本文用QCD因子化方法,对Bc→J/ψπ,ηcπ,J/ψK,ηcK进行唯象研究,给出它们的分支比,并对理论预言的不确定性进行分析.
The Large Hadron Collider (LHC) is scheduled to run in 2008. The expected large production rates at the LHC make the study of Bc mesons highly interesting. In this paper, the Bc→J/ψπ,ηcπ,J/ψK,ηcK, ricK decays are studied with the QCD factorization approach. Their branching ratios are obtained, The theoretical uncertainties are discussed in detail.
