O(a)改进的重-轻算子的格重整化:补遗

Lattice renormalisation of O(a) improved heavy-light operators: an addendum

Benoit Blossier

摘要:

本文在重夸克有效理论的框架下,采用改进的规范作用量,在单圈微扰理论下,给出了3维静轻流的重整化常数的解析表达式和数值。这完成了几年前开始的工作,实际上是欧洲扭曲质量合作组织[arXiv:1107.1441[hep-lat]]测量衰变常数$f_{B}$和$f_{B_{s}}$的中间步骤。

英文摘要:

The analytical expressions and the numerical values of the renormalisation constants of dimension 3 static-light currents are given at one-loop order of perturbation theory in the framework of Heavy Quark Effective Theory and with an improved gauge action: the static quark is described by the HYP-smeared action and the light quark is of Wilson kind. This completes a work started few years ago and is actually an intermediate step in the measurement of the decay constants $f_{B}$ and $f_{B_{s}}$ by the European Twisted Mass Collaboration [arXiv:1107.1441[hep-lat]].
