Lattice QCD Applications on QPACE
Y. Nakamura, A. Nobile, D. Pleiter +4
QPACE is a novel massively parallel architecture optimized for lattice QCD simulations. A single QPACE node is based on the IBM PowerXCell 8i processor. The nodes are interconnecte…
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…
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…
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…
