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…
