Physical and unphysical effects in the mixed SU(2)/SO(3) gauge theory
P. W. Stephenson
We investigate possible problems with universality in lattice gauge theory where a mixed fundamental SU(2) and SO(3)-invariant gauge group is used: the (second order) finite temper…

New results from mixed-action lattice gauge theory
Peter Stephenson
We extend and attempt to clarify recent results which showed possible problems for universality for the gauge group SU(2). We suggest that the presence of artifacts actually distor…

The running coupling from lattice gauge theory:
P. W. Stephenson
I discuss some calculations of the running coupling in SU() gauge theories from lattice simulations, centering on the work of the UKQCD collaboration. This talk is introductory…
