轻重赝标介子的半轻子衰变

Semileptonic decays of heavy-light pseudoscalar mesons

Nazario Tantalo

摘要:

我讨论了最近的淬火晶格计算的结果的两个独立的形状因子参数化的半轻子衰变之间的重轻赝标介子。在动量转移不为零的情况下,计算了轻子l=e,μ和轻子质量不为零的情况下B → Dlnu过程的微分衰变率。

英文摘要:

I discuss the results of a recent quenched lattice calculation of the two independent form factors parametrizing the semileptonic decays between heavy-light pseudoscalar mesons. The differential decay rate of the process B --> D l nu has been calculated at non vanishing momentum transfer both in the case of the light leptons, l=e,mu, and in the case of a non vanishing lepton mass, l=tau.
