B-physics from non-perturbatively renormalized HQET in two-flavour lattice QCD
Fabio Bernardoni, Benoit Blossier, John Bulava +7
We report on the ALPHA Collaboration's lattice B-physics programme based on N_f=2 O(a) improved Wilson fermions and HQET, including all NLO effects in the inverse heavy quark mass,…
Improved interpolating fields for hadrons at non-zero momentum
Michele Della Morte, Benjamin Jaeger, Thomas Rae +1
We generalize Gaussian/Wuppertal smearing in order to produce non-spherical wave functions. We show that we can achieve a reduction in the noise-to-signal ratio for correlation fun…
The nucleon axial charge from lattice QCD with controlled errors
S. Capitani, M. Della Morte, G. von Hippel +5
We report on our calculation of the nucleon axial charge gA in QCD with two flavours of dynamical quarks. A detailed investigation of systematic errors is performed, with a particu…
Parameters of Heavy Quark Effective Theory from Nf=2 lattice QCD
Benoit Blossier, Michele Della Morte, Patrick Fritzsch +5
We report on a non-perturbative determination of the parameters of the lattice Heavy Quark Effective Theory (HQET) Lagrangian and of the time component of the heavy-light axial-vec…
