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

Benoit Blossier
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]].
