Bulk-preventing actions for SU(N) gauge theories
Tobias Rindlisbacher🇨🇭 · Kari Rummukainen🇫🇮 · Ahmed Salami🇫🇮
Abstract
We introduce a one-parameter family of SU(N) gauge actions which, when used in combination with an HMC update algorithm, prevent the gauge system from entering an artificial bulk-"phase". We briefly discuss the mechanism behind the bulk-prevention and present test results for different SU(N) gauge groups.
