![]() | DeTar, Carleton | Results for light pseudoscalars from three-flavor simulations | We compute pseudoscalar meson masses and decay constants in partially quenched QCD with three dynamical flavors of improved staggered quarks. Fitting the lattice data to staggered chiral perturbation theory (SX_x001F_PT) forms and extrapolating in quark mass and lattice spacing, we find: frr = 129... | Pseudoscalars; Decay constants; Staggered quarks | 2005-03 |
