B meson spectrum and decay constant from Nf=2 simulations
Benoit Blossier, John Bulava, Michele Della Morte +8
We report on the status of an ALPHA Collaboration project to extract quantities for B physics phenomenology from Nf=2 lattice simulations. The framework is Heavy Quark Effective Th…
Improved automated lattice perturbation theory in background field gauge
T. C. Hammant, R. R. Horgan, C. J. Monahan +5
We present an algorithm to automatically derive Feynman rules for lattice perturbation theory in background field gauge. Vertices with an arbitrary number of both background and qu…
The b quark mass from lattice nonrelativistic QCD
Alistair Hart, Georg von Hippel, R. R. Horgan +2
We present the first two-loop calculation of the heavy quark energy shift in lattice nonrelativistic QCD (NRQCD). This calculation allow us to extract a preliminary prediction of $…
HQET at order 1/m: III. Decay constants in the quenched approximation
Benoît Blossier, Michele Della Morte, Nicolas Garron +4
We report on the computation of the meson decay constant in Heavy Quark Effective Theory on the lattice. The next to leading order corrections in the HQET expansion are inclu…
HQET at order : II. Spectroscopy in the quenched approximation
Benoît Blossier, Michele Della Morte, Nicolas Garron +4
Using Heavy Quark Effective Theory with non-perturbatively determined parameters in a quenched lattice calculation, we evaluate the splittings between the ground state and the firs…
