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…
Charge Symmetry Breaking in Parton Distribution Functions from Lattice QCD
R. Horsley, Y. Nakamura, D. Pleiter +7
By determining the quark momentum fractions of the octet baryons from N_f=2+1 lattice simulations, we are able to predict the degree of charge symmetry violation in the parton dist…
Very high order lattice perturbation theory for Wilson loops
R. Horsley, G. Hotzel, E. -M. Ilgenfritz +5
We calculate perturbative Wilson loops of various sizes up to loop order at different lattice sizes for pure plaquette and tree-level improved Symanzik gauge theories using…
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…
