Topological susceptibility with the improved Asqtad action
C. Bernard, T. DeGrand, C. DeTar +9
Chiral perturbation theory predicts that in quantum chromodymamics light dynamical quarks suppress the topological (instanton) susceptibility. We investigate this suppression throu…
Excited States in Staggered Meson Propagators
MILC Collaboration, C. Bernard, T. Burch +7
We report on preliminary results from multi-particle fits to meson propagators with three flavors of light dynamical quarks. We are able to measure excited states in propagators wi…
Pion and kaon physics with improved staggered quarks
MILC Collaboration, C. Aubin, C. Bernard +8
We compute pseudoscalar meson masses and decay constants using staggered quarks on lattices with three flavors of sea quarks and lattice spacings fm and $\approx 0.0…
Hybrid configuration content of heavy S-wave mesons
Tommy Burch, Doug Toussaint
We use the non-relativistic expansion of QCD (NRQCD) on the lattice to study the lowest hybrid configuration contribution to the ground state of heavy S-wave mesons. Using lowest-o…
Lattice calculation of hybrid mesons with improved Kogut-Susskind fermions
C. Bernard, T. Burch, C. DeTar +6
We report on a lattice determination of the mass of the exotic hybrid meson using an improved Kogut-Susskind action. Results from both quenched and dynamical quark simulat…
