摘要：

We present results of a lattice simulation of quantum chromodynamics with two degenerate flavors of dynamic Wilson fermions at 6/g2= 5.3 at each of two dynamical fermion hopping parameters kappa = 0.1670 and 0.1675 corresponding to pion masses in lattice units of about 0.45 and 0.31. The simulations include three other values of valence quark mass, in addition to the dynamical quarks. We present calculations of masses and of the decay constants of vector mesons and of pseudoscalars, including the D-meson decay constant. The effects of sea quarks on matrix elements and spectroscopy are small.
