Nucleon sigma terms for 2+1 quark flavours
R. Horsley, Y. Nakamura, H. Perlt +7
QCD lattice simulations yield hadron masses as functions of the quark masses. From the gradients of the hadron masses the sigma terms can then be determined. We consider here dynam…
Disconnected contributions to D-meson semi-leptonic decay form factors
G. S. Bali, S. Collins, R. Horsley +9
We calculate the disconnected contribution to the form factor for the semileptonic decay of a D-meson into a final state, containing a flavor singlet eta meson. We use QCDSF n_f=2+…
Hyperon sigma terms for 2+1 quark flavours
R. Horsley, Y. Nakamura, H. Perlt +7
QCD lattice simulations determine hadron masses as functions of the quark masses. From the gradients of these masses and using the Feynman-Hellmann theorem the hadron sigma terms c…
Dirac and Pauli form factors from lattice QCD
S. Collins, M. Göckeler, Ph. Hägler +11
We present a comprehensive analysis of the electromagnetic form factors of the nucleon from a lattice simulation with two flavors of dynamical O(a)-improved Wilson fermions. A key…
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…
