Hyperon Form Factors from N_f=2+1 QCD
M. Göckeler, Ph. Hägler, R. Horsley +8
We present results from the QCDSF/UKQCD collaboration for the electromagnetic and semi-leptonic form factors for the hyperons. The simulations are performed on our new ensembles ge…
Flavour symmetry breaking and tuning the strange quark mass for 2+1 quark flavours
W. Bietenholz, V. Bornyakov, M. Göckeler +14
QCD lattice simulations with 2+1 flavours typically start at rather large up-down and strange quark masses and extrapolate first the strange quark mass to its physical value and th…
Disconnected contributions to hadronic structure
Sara Collins, Gunnar Bali, Andrea Nobile +3
We present an update of an on-going project to determine the disconnected contributions to hadronic structure, specifically, the scalar matrix element and the quark contribution to…
BQCD - Berlin quantum chromodynamics program
Yoshifumi Nakamura, Hinnerk Stüben
We publish BQCD as free software under the GNU General Public License. BQCD is a Hybrid Monte-Carlo program that simulates lattice QCD with dynamical Wilson fermions. It is one of…
Renormalisation of composite operators in lattice QCD: perturbative versus nonperturbative
M. Göckeler, R. Horsley, Y. Nakamura +8
The perturbative and nonperturbative renormalisation of quark-antiquark operators in lattice QCD with two flavours of clover fermions is investigated within the research programme…
Non-perturbative improvement of stout-smeared three flavour clover fermions
N. Cundy, M. Göckeler, R. Horsley +11
We discuss a 3-flavour lattice QCD action with clover improvement in which the fermion matrix has single level stout smearing for the hopping terms together with unsmeared links fo…
