Baryon Axial Charges and Momentum Fractions with N_f=2+1 Dynamical Fermions
M. Göckeler, Ph. Hägler, R. Horsley +8
We report on recent results of the QCDSF/UKQCD Collaboration on investigations of baryon structure using configurations generated with N_f=2+1 dynamical flavours of O(a) improved W…
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…
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…
Determination of Light and Strange Quark Masses from Full Lattice QCD
M. Göckeler, R. Horsley, A. C. Irving +4
We compute the light and strange quark masses m_l = (m_u+m_d)/2 and m_s, respectively, in full lattice QCD with N_f=2 flavors of light dynamical quarks. The renormalization constan…
Axial and tensor charge of the nucleon with dynamical fermions
A. Ali Khan, M. Göckeler, P. Hägler +9
We present preliminary results for the axial and tensor charge of the nucleon obtained from simulations with N_f=2 clover fermions. A comparison with chiral perturbation theory is…
