| 英文摘要 | We choose a correlation function of chiral current to calculate the form factors f(B pi)(+)(q(2)), (f) over tilde (B pi)(q(2)) and the scalar form factor of f(0)(q(2)), thereby we can study the effect of leptonic mass on B-0 -> pi(-) l(+) (v) over tilde (i) (l = e, mu, tau) decay. In this paper, we calculate the branching ratio of B-0 -> pi(-) l(+) (v) over tilde (i) (l = e, mu, tau) decay for the first time, and find the leptonic mssses m(e) and m(mu) may be ignored, but the heavy leptonic mass m(tau), may not be ignored and it can affect the branching ratio. The calculation results are consistent with the experimental data. |
