On the running of the bare coupling in SU(N) lattice gauge theories
Chris Allton, Michael Teper, Aurora Trivini
Interpreting the way that the SU(3) bare lattice coupling runs with the lattice spacing is complicated by the fact that there is a smooth cross-over region in which the strong coup…
The running of the bare coupling in SU(N) gauge theories
Chris Allton, Michael Teper, Aurora Trivini
For N>4 there is a first order bulk transition that cleanly separates the strong and weak coupling regimes of SU(N) lattice gauge theories with the plaquette action. We find that i…
Charmonium at high temperature in two-flavor QCD
Gert Aarts, Chris Allton, Mehmet Bugrahan Oktay +2
We compute charmonium spectral functions in 2-flavor QCD on anisotropic lattices using the maximum entropy method. Our results suggest that the S-waves (J/psi and eta_c) survive up…
Recent Results from (Full) Lattice QCD
Chris Allton
An overview of the Lattice technique for studies of the strong interaction is given. Recent results from the UKQCD lattice collaboration are presented. These concentrate on spectra…
Lattice Monte Carlo Data versus Perturbation Theory
C. R. Allton
The differences between lattice Monte Carlo data and perturbation theory are usually associated with the ``bad'' behaviour of the bare lattice coupling g_0 due to the effects of la…
