Matrix elements and baryon spectroscopy from unquenched lattice QCD with improved staggered quarks
Abstract
We look for the effect of open decay channels on the masses of baryons in unquenched lattice QCD. We apply variational smearing using fuzzed basis states to a staggered nucleon operator. The signal for the sbar s current in the nucleon is studied. The lattice calculations are done using improved staggered fermions.
