- W1246753509 abstract "摘要 通过构造适当的关联函数,计算B→π跃迁形状因子f+Bπ(q2),f Bπ(q2)和标量形状因子f0(q2),从而就能研究轻子质量对B0→π 关键词: B介子半轻衰变 / 形状因子 / 分支比 Abstract We choose a correlation function of chiral current to calculate the form factors f+Bπ(q2), f Bπ(q2) and the scalar form factor of f0(q2), thereby we can study the effect of leptonic mass on B0→π－l+ν l (l=e, μ, τ) decay. In this paper, we calculate the branching ratio of B0→π－l+ν l(l=e, μ, τ) decay for the first time, and find the leptonic mssses me and mμ may be ignored, but the heavy leptonic mass mτ may not be ignored and it can affect the branching ratio. The calculation results are consistent with the experimental data.
