Nucleon axial charge and pion decay constant from two-flavor lattice QCD

R. Horsley, Y. Nakamura, A. Nobile +3

The axial charge of the nucleon and the pion decay constant are computed in two-flavor lattice QCD. The simulations are carried out on lattices of various volumes and l…

<x>_{u-d} from lattice QCD at nearly physical quark masses

Gunnar S. Bali, Sara Collins, Mridupawan Deka +7

We determine the second Mellin moment of the isovector quark parton distribution function <x>_{u-d} from lattice QCD with N_f=2 sea quark flavours, employing the non-perturbatively…

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…

Deflation and Flexible SAP-Preconditioning of GMRES in Lattice QCD Simulation

Andreas Frommer, Andrea Nobile, Paul Zingler

The simulation of lattice QCD on massively parallel computers stimulated the development of scalable algorithms for the solution of sparse linear systems. We tackle the problem of…

First moments of the nucleon generalized parton distributions from lattice QCD

A. Sternbeck, M. Göckeler, Ph. Hägler +8

We report on our lattice calculations of the nucleon's generalized parton distributions (GPDs), concentrating on their first moments for the case of N_f=2. Due to recent progress o…

Strangeness Contribution to the Proton Spin from Lattice QCD

Gunnar S. Bali, Sara Collins, Meinulf Gockeler +8

We compute the strangeness and light-quark contributions Delta s, Delta u and Delta d to the proton spin in nf=2 lattice QCD at a pion mass of about 285 MeV and at a lattice spacin…
