论文摘要
在本次演讲中,我简要地回顾了包含$ b $衰减理论的当前状态:$ \ bar b \ to x_c \,\ ell \,\ ell \,\barν_\ ell $,$ \ bar b \ to x_u \,\ ell \,\ ell \ \ ell \,\barν_\ ell $,and $ \ bar b b \ bar b \ f \ f \ x_s \ th x_s \ th x_s \ f to。我试图回答三个问题:当前的“最先进的状态”是什么,可以改善理论预测,并会导致较小的理论不确定性。
In this talk I briefly review the current status of the theory of the inclusive $B$ decays: $\bar B\to X_c\, \ell\,\barν_\ell$, $\bar B\to X_u\, \ell\,\barν_\ell$, and $\bar B\to X_s\,γ$. I try to answer three questions: what is the current "state of the art", can the theoretical prediction be improved, and will it lead to a smaller theoretical uncertainty.
