A non-perturbative study of the renormalisation of action parameters in anisotropic lattice QCD with applications to finite temperature QCD

Abstract

The advantages of using anisotropic lattices, instead of the more usual isotropic lattices, in QCD simulations are well estabhshed. Anisotropic lattices can be used to increase signal resolution and allow computational overhead to be kept to a minimum while minimising finite volume effects. A fine temporal discretisation can be used to suppress mass-dependent errors which has considerable advantages; particularly for heavy quark simulations. Finite temperature field theory has a natural asymmetry which is ideally suited to an anisotropic lattice formulation.
