摘要:We report on our lattice calculations of the nucleon’s generalized parton distributions (GPDs), concentrating on their first moments for the case of Nf = 2. Due to recent progress on the numerical side we are able to present results for the generalized form factors at pion masses as low as 260 MeV. We perform a fit to one-loop covariant baryon chiral perturbation theory with encouraging results.
