Effects of Dynamical Quarks in UKQCD Simulations
Chris Allton
Abstract
Recent results from the UKQCD Collaboration's dynamical simulations are presented. The main feature of these ensembles is that they have a fixed lattice spacing and volume, but varying sea quark mass from infinite (corresponding to the quenched simulation) down to roughly that of the strange quark mass. The main aim of this work is to uncover dynamical quark effects from these ``matched'' ensembles. We obtain some evidence of dynamical quark effects in the static quark potential with less effects in the hadronic spectrum.
