Nucleon generalized form factors from lattice QCD with nearly physical quark masses

الأصل · EN

We determine generalized form factors of the nucleon from lattice simulations with Nf = 2 mass-degenerate non-perturbatively improved Wilson-Sheikholeslami-Wohlert fermions down to a pion mass of 150 MeV. We also present the resulting isovector quark angular momentum. Possible excited-state contaminations are investigated with correlated simultaneous fits.
