Author(s): G. C. Donald, C. T. H. Davies, R. J. Dowdall, E. Follana, K. Hornbostel, J. Koponen, G. P. Lepage, and C. McNeile (HPQCD Collaboration) We calculate the J / ψ mass, leptonic width and radiative decay rate to γ η c from lattice QCD including u , d and s quarks in the sea for the first time. We use the highly improved staggered quark formalism and nonperturbatively normalized vector currents for the leptonic and radiative decay rates. Our ... [Phys. Rev.
