Efficient glueball simulations on anisotropic lattices

Abstract

Monte Carlo results for the low-lying glueball spectrum using an improved, anisotropic action are presented. Ten simulations at lattice spacings ranging from 0.2 to 0.4 fm and two different anisotropies have been performed in order to demonstrate the advantages of using coarse, anisotropic lattices to calculate glueball masses. Our determinations of the tensor ${(2}^{++})$ and pseudovector ${(1}^{+\ensuremath{-}})$ glueball masses are more accurate than previous Wilson action calculations.
