Aspects of determining fBs: scaling and power-law divergences
S. Collins, C. T. H. Davies, J. Hein +3
We present preliminary results for the decay constant of the Bs meson, fBs, at three values of beta=5.7, 6.0 and 6.2 using NRQCD and clover fermions for the heavy and light quarks…
News from the lattice
C. Morningstar
A summary of some recent results from lattice simulations is presented. These include first calculations of the strangeness magnetic moment of the nucleon, three new studies of the…
Gluon excitations of the static-quark potential
K. J. Juge, J. Kuti, C. Morningstar
The spectrum of gluon excitations in the presence of a static quark-antiquark pair is presented. Our results are obtained from computer simulations of gluons on anisotropic space-t…
Glueballs from Improved Lattice Actions
Colin Morningstar, Mike Peardon
The low-lying glueball masses and the hadronic scale are computed in lattice SU(3) gauge theory with the aim of establishing the effectiveness of the improved action approach…
Core -- a New Method for Solving Hamiltonian Lattice Systems
Colin Morningstar, Marvin Weinstein
The COntractor REnormalization group (CORE) approximation, a new method for solving Hamiltonian lattice systems, is introduced. The approach combines variational and contraction te…
