Topological susceptibility and Instanton size distribution from over-improved cooling
arXiv:hep-lat/9509081 · doi:10.1016/0920-5632(96)00056-4
Abstract
We measure the topological susceptibility by cooling with an over-improved action. In contrast with usual cooling, large instantons survive over-improved cooling {\em indefinitely}. By varying the parameter of the over-improved cooling action, we measure the instanton size distribution.
