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…
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…
Nucleon form factors and structure functions
S. Collins, M. Göckeler, Ph. Hägler +13
We give an update on our ongoing efforts to compute the nucleon's form factors and moments of structure functions using Nf=2 flavours of non-perturbatively improved Clover fermions…
