摘要：

We analyze the semileptonic B-c - B(u)(*)l(+)l(-) decay in the framework of the Standard Model. We calculate the B-c to B-u(*) transition form factors in QCD sum rules. Analytical expressions for the spectral densities and gluon condensates are presented. The branching ratio of the B-c -> B(u)(*)l(+)l(-) decay is calculated, and it is obtained that this decay can be detectable at forthcoming LHC machines.
