Effective heavy-light meson energies in small-volume quenched QCD
Jochen Heitger, Jan Wennekers
We study effective energies of heavy-light meson correlation functions in lattice QCD and a small volume of (0.2 fm)^4 to non-perturbatively calculate their dependence on the heavy…
A non-perturbative computation of the B-meson decay constant and the b-quark mass in HQET
Jochen Heitger
A lattice computation of the B-meson decay constant and the mass of the b-quark to leading order in the heavy quark effective theory is presented. The involved renormalization prob…
Non-perturbative Heavy Quark Effective Theory
Jochen Heitger, Rainer Sommer
We explain how to perform non-perturbative computations in HQET on the lattice. In particular the problem of the subtraction of power-law divergences is solved by a non-perturbativ…
from twisted mass QCD
P. Dimopoulos, J. Heitger, C. Pena +2
We present some preliminary results for at , using the twisted mass QCD formalism for the computation of bare matrix elements of the operator. The main advantag…
Quark bilinear step scaling functions and their continuum limit extrapolation
M. Guagnelli, J. Heitger, C. Pena +1
Some new results on nonperturbative renormalisation of quark bilinears in quenched QCD with Schroedinger Functional techniques are presented. Special emphasis is put on a study of…
Static quarks with improved statistical precision
M. Della Morte, S. Durr, J. Heitger +4
We present a numerical study for different discretisations of the static action, concerning cut-off effects and the growth of statistical errors with Euclidean time. An error reduc…
