摘要：The effect of using smeared sink operators on the hadron spectrum is studied for quenched twisted
mass lattice QCD with up, down, and strange quarks. Gaussian smearing is used for quark elds,
and stout link smearing for gauge elds. Smeared correlators are found to be dominated by the
ground state with a small contribution from excited states, leading to an improved determination
of some ground state masses.
