Author(s): Gunnar S. Bali, Sara Collins, Mridupawan Deka, Benjamin Gläßle, Meinulf Göckeler, Johannes Najjar, Andrea Nobile, Dirk Pleiter, Andreas Schäfer, and André Sternbeck 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 flavors, employing the nonperturbatively improved Wilson-Sheikholeslami-Wohlert action at a pseudoscalar mass m π =157(6) MeV. The result is converted nonperturbativel... [Phys. Rev. D 86, 054504] Published Tue Sep 11, 2012
