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…
An Update on Distribution Amplitudes of the Nucleon and its Parity Partner
R. W. Schiel, G. S. Bali, V. M. Braun +12
The calculation of baryon wave functions at small inter-quark separations is an ongoing effort within the QCDSF collaboration. In this update on normalization constants and distrib…
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…
Flavour blindness and patterns of flavour symmetry breaking in lattice simulations of up, down and strange quarks
W. Bietenholz, V. Bornyakov, M. Göckeler +12
QCD lattice simulations with 2+1 flavours (when two quark flavours are mass degenerate) typically start at rather large up-down and strange quark masses and extrapolate first the s…
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…
