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…
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…
Continuum Limit Physics from 2+1 Flavor Domain Wall QCD
Y. Aoki, R. Arthur, T. Blum +23
We present physical results obtained from simulations using 2+1 flavors of domain wall quarks and the Iwasaki gauge action at two values of the lattice spacing , (=\,1.7…
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…
K->pi form factors with reduced model dependence
P. A. Boyle, J. M. Flynn, A. Juttner +6
Using partially twisted boundary conditions we compute the K->pi semi-leptonic form factors in the range of momentum transfers 0 <~ q^2 <= q^2_{max}=(mK-mpi)^2 in lattice QCD with…
