![]() | DeTar, Carleton | Topological susceptibility with the improved Asqtad action | As a test of the chiral properties of the improved Asqtad (staggered fermion) action, we have been measuring the topological susceptibility as a function of quark masses for 2 + 1 dynamical flavors. We report preliminary results, which show reasonable agreement with leading order chiral perturbatio... | Topological cbarge; Staggered fermions | 2003-05 |
