摘要We in terms of optical theorem estimate the lifetime of B-c meson with the parameters which are determined by fitting the data for the lifetimes and inclusive semileptonic decays of various B and D mesons. In the estimation, we find that the bound-state effects are important, and take them into account carefully in the framework which attributes the effects to the effective masses of the decay heavy quarks in the inclusive processes. We also find that to B, lifetime the penguin contribution is enhanced due to possible interference between the penguin and the 'tree part' c(1)O(1) + c(2)O(2).
