论文摘要
考虑到$ b $中的波波函数$ ϕ_ {b2} $，$ b $ $ {\ to} $ $ $ pv $衰减在标准型号中使用扰动QCD方法的三种情况下，在领先的订单上重新列出，其中$ p $ = $ = $ = $ $ $ $ $ y $ k $和$ k $，$ v $ $ v $ deceotes the Cheep $ seafor the Floack $ sus $ sus $ soss $ soss（3）$（3）。发现从$ ϕ_ {b2} $中的贡献可以提高大多数分支比率，并且有助于提高更新的计算和可用数据之间分支比的总体一致性，尽管实验和理论结果之间仍然存在几个差异。
Considering the $B$ mesonic wave function $ϕ_{B2}$, the $B$ ${\to}$ $PV$ decays are restudied at the leading order for three scenarios using the perturbative QCD approach within the standard model, where $P$ $=$ $π$ and $K$, and $V$ denotes the ground $SU(3)$ vector mesons. It is found that contributions from $ϕ_{B2}$ can enhance most branching ratios, and are helpful for improving the overall consistency of branching ratios between the updated calculations and available data, although there are still several discrepancies between the experimental and theoretical results.
