Charm quark mass and D-meson decay constants from two-flavour lattice QCD
Jochen Heitger, Georg M. von Hippel, Stefan Schaefer +1
We present a computation of the charm quark's mass and the leptonic D-meson decay constants f_D and f_{D_s} in two-flavour lattice QCD with non-perturbatively O(a) improved Wilson…
Vector correlator and scale determination in lattice QCD
Anthony Francis, Georg von Hippel, Fred Jegerlehner +1
We implement a proposal made in [arXiv:1107.4388] to determine the lattice spacing by matching the lattice vector correlator at a reference distance scale with the same correlator…
A high-statistics study of the nucleon EM form factors, axial charge and quark momentum fraction
B. Jäger, T. D. Rae, S. Capitani +6
We present updated results for the nucleon axial charge and electromagnetic (EM) form factors, which include a significant increase in statistics for all ensembles (up to 4000 meas…
The b-quark mass from non-perturbative Heavy Quark Effective Theory at
F. Bernardoni, B. Blossier, J. Bulava +8
We report our final estimate of the b-quark mass from lattice QCD simulations using Heavy Quark Effective Theory non-perturbatively matched to QCD at . Treating s…
B-physics with Wilson fermions
F. Bernardoni, B. Blossier, J. Bulava +8
We report the final results of the ALPHA collaboration for some B-physics observables: , and . We employ CLS configurations with 2 flavors of improved Wi…
The scalar pion form factor in two-flavor lattice QCD
Vera Gülpers, Georg von Hippel, Hartmut Wittig
We calculate the scalar form factor of the pion using two dynamical flavors of non-perturbatively -improved Wilson fermions, including both the connected and the di…
The Shape of Covariantly Smeared Sources in Lattice QCD
Georg M. von Hippel, Benjamin Jäger, Thomas D. Rae +1
Covariantly smeared sources are commonly used in lattice QCD to enhance the projection onto the ground state. Here we investigate the dependence of their shape on the gauge field b…
Radiative improvement of the lattice NRQCD action using the background field method with applications to quarkonium spectroscopy
T. C. Hammant, A. G. Hart, G. M. von Hippel +2
We apply the background field (BF) method to Non-Relativistic QCD (NRQCD) on the lattice in order to determine the one-loop radiative corrections to the coefficients of the NRQCD a…
