摘要:We report new data for the topological susceptibility computed on 2+1 flavor dynamical configurations
with lattice spacing 0.06 fm, generated with the asqtad action. The topological susceptibility
is computed by HYP smearing and compared with rooted staggered chiral perturbation
theory as the pion mass goes to zero. At 0.06 fm, the raw data is already quite close to the continuum
extrapolated values obtained from coarser lattices. These results provide a further test of
the asqtad action with rooted staggered flavors.
