BR(抗B--> Xs γ)中的精密度计算

Precision calculations in BR(anti-B --> Xs gamma)

Thorsten Ewerth

摘要:

简要介绍了\bar{B} \to X_sγ衰变率微扰计算和非微扰功率修正的研究现状。

英文摘要:

We briefly summarize the current status of perturbative calculations at next-to-next-to-leading-order (NNLO) accuracy in the \bar{B}\to X_sγdecay rate as well as that of non-perturbative power-corrections.
