半轻子衰变:重子夸克极限

Semileptonic Decays: The Heavy Daughter Quark Limit

Matthew Dowling

摘要:

在b夸克和c夸克质量相等的情况下,我们计算了b -> clv衰变到α_s的二级衰变率。这里的结果证实了最近在相反的极限下所做的计算,其中c夸克比b夸克轻得多。

英文摘要:

We have calculated the rate of the decay b -> clv to second order in alpha_s in the limit that the b and c quarks have equal masses. The results here confirm recent calculations done in the opposite limit where the c-quark is much lighter than the b-quark.
