重夸克衰变的最小处方修正谱

Minimal prescription corrected spectra in heavy quark decays

Leonardo Di Giustino, Giulia Ricciardi, Luca Trentadue

摘要:

本文应用最小处方方法驯服了重夸克衰变图解公式的朗道极奇异性。考虑了末态夸克质量的影响。对于冻结耦合近似和QCD运行耦合情形,得到了t->b和b->c跃迁的显式表达式。

英文摘要:

The Minimal Prescription procedure is applied to tame the Landau pole singularities of resummed formulae for heavy quark decays. Effects of the final quark mass are taken into account. Explicit expressions are obtained for the t->b and b->c transitions for both the frozen coupling approximation and in the QCD running coupling case.
