摘要：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 ¯ ss current in the nucleon is studied. The lattice calculations are done using improved
staggered fermions.
