Nucleon mass and sigma term from lattice QCD with two light fermion flavors
G. S. Bali, P. C. Bruns, S. Collins +16
We analyze Nf=2 nucleon mass data with respect to their dependence on the pion mass down to mpi = 157 MeV and compare it with predictions from covariant baryon chiral perturbation…
Finite volume corrections to the electromagnetic current of the nucleon
Ludwig Greil, Thomas R. Hemmert, Andreas Schäfer
We compute corrections to both the isovector anomalous magnetic moment and the isovector electromagnetic current of the nucleon to in the framework of covariant two-flavor…
Sigma term and strangeness content of octet baryons
S. Durr, Z. Fodor, T. Hemmert +11
By using lattice QCD computations we determine the sigma terms and strangeness content of all octet baryons by means of an application of the Hellmann-Feynman theorem. In addition…
Chiral extrapolation of nucleon wave function normalization constants
Philipp Wein, Peter C. Bruns, Thomas R. Hemmert +1
Within the framework of two-flavor covariant baryon chiral perturbation theory we have expressed the Chernyak-Zhitnitsky, Ioffe and Dosch currents in terms of chiral fields to prov…
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…
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…
