Abstract

The radiative and pureleptonic decays of B_cmesons are of hadrons uncertainty in theoretical calculations. Using three types of the B_c meson wave functions which describe the characteristics of the QCD nonperturbative and by controlling the parameters in them, the uncertainties of B_c meson decay caused by the hadron decay model are studied in detail. The theoretical results show the branching ratios are (1.819 81~3.189 61)×10^-5, which are sensitive to the type of wave functions.
