Pierro, Massimo Di

We use the dynamical gluon configurations provided by the MILC collaboration in a study of the charmonium spectrum and {psi} leptonic width. We examine sea quark effects on mass splitting and on the leptonic decay matrix element for light masses as low as m{sub s}/5, while keeping the strange quark mass fixed and the lattice spacing nearly constant.
