Varnhorst (Budapest-Marseille-Wuppertal Collaboration) We present a QCD calculation of the u , d , and s scalar quark contents of nucleons based on 47 lattice ensembles with N f = 2 + 1 dynamical sea quarks, 5 lattice spacings down to 0.054 fm, lattice sizes up to 6 fm, and pion masses down to 120 MeV. Using the Feynman-Hellmann theorem, we obtain f u d N = 0.0405 ( … [Phys. Rev. Lett. 116, 172001] Published Thu Apr 28, 2016
