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

High Energy Physics - Lattice 2013-05-29 v3

Abstract

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 fBf_{B} and fBsf_{B_{s}} by the European Twisted Mass Collaboration [arXiv:1107.1441[hep-lat]].
