Non-perturbative renormalization of the static axial current in quenched QCD
Jochen Heitger, Martin Kurth, Rainer Sommer
We non-perturbatively calculate the scale dependence of the static axial current in the Schroedinger functional scheme by means of a recursive finite-size scaling technique, taking…
Non-perturbative determination of Z_A^{stat} in quenched QCD
Jochen Heitger, Martin Kurth, Rainer Sommer
We non-perturbatively calculate the renormalization factor of the static axial vector current in O(a) improved quenched lattice QCD. Its scale dependence is mapped out in the Schro…
An explicit example of HQET at one-loop order of perturbation theory
Martin Kurth, Rainer Sommer
As an explicit example of HQET, we construct correlation functions containing a heavy-light axial current, both in the static approximation and in full QCD. This enables us to inve…
Heavy Quark Effective Theory at one-loop order: An explicit example
ALPHA Collaboration, Martin Kurth, Rainer Sommer
We consider correlation functions containing the axial current of one light and one heavy quark in the static approximation as well as in full QCD, using the lattice regularization…
Renormalization and O(a)-improvement of the static-light axial current
Martin Kurth, Rainer Sommer
A systematic treatment of O(a)-improvement in lattice theories with static quarks is presented. The Schrödinger functional is discussed and a renormalization condition for the stat…
Renormalization of the static-light axial current
Martin Kurth, Rainer Sommer
We discuss the determination of the heavy-light axial current renormalization in the static approximation, using a new method based on the Schrödinger Functional (SF). Previous per…
