摘要:

我们回顾了各种B介子衰变,需要的知识的横向衰变常数的b1(1235)介子。本文报道了用格点量子色动力学对b1介子横向衰变常数的探索性计算。格点量子色动力学的计算使用了两种格点间距的非猝灭规范组态,由两种海夸克产生。使用了扭曲质量形式。

英文摘要:

We review various B meson decays that require knowledge of the transverse decay constant of the b1(1235) meson. We report on an exploratory lattice QCD calculation of the transverse decay constant of the b1 meson. The lattice QCD calculations used unquenched gauge configurations, at two lattice spacings, generated with two flavours of sea quarks. The twisted mass formalism is used.
