Simple hadronic matrix elements with Wilson valence quarks and dynamical staggered fermions at 6g2=5.6

We have measured some simple matrix elements for pseudoscalar and vector mesons made of Wilson valance quarks and staggered sea quarks at β=5.6 at sea quark masses amq=0.01and0.025. Our measurements include the decay constants of pseudoscalars (including fD), the wave function at the origin (or decay constant) of vector mesons, and the calculation of quark masses from current algebra. The effects of sea quarks on the simulations are small. We make comparisons to quenched simulations at similar values of the lattice spacing 2 GeV).
