Improving Lattice Quark Actions
M. Alford, T. R. Klassen, G. P. Lepage
We explore the first stage of the Symanzik improvement program for lattice Dirac fermions, namely the construction of doubler-free, highly improved classical actions on isotropic a…
Towards Highly Improved Quark Actions
M. G. Alford, T. R. Klassen, G. P. Lepage
We describe two ideas useful in the construction of highly improved quark actions for simulations on coarse lattices: (1) Field transformations to solve the doubler problem without…
The Deconfinement Transition on Coarse Lattices
D. W. Bliss, K. Hornbostel, G. P. Lepage
We compute the critical temperature for the deconfinement transition of pure QCD on coarse lattices, with , and lattice spacings from .33 fm to .15 fm. We empl…
Spectroscopy from Lattice QCD
C. T. H. Davies, K. Hornbostel, G. P. Lepage +3
We present first results for spectroscopy using Lattice Non-Relativistic QCD (NRQCD). For the NRQCD action the leading order spin-dependent and next to leading order spin-ind…
