The effect of using smeared sink operators on the hadron spec trum is studied for quenched twisted mass lattice QCD with up, down, and strange quarks. Gaussian mearing is used for quark fields, andâ€¦ (More)

Extraction of the mass spectrum from twisted mass lattice QCD is facilitated by respecting the octahedral group of rotations and accommodating the broken parity and flavor symmetries of the theory.â€¦ (More)
