Quenched Heavy-Light Decay Constants
UKQCD Collaboration
We present results for heavy-light decay constants, using both propagating quarks and the static approximation, in O(a)-improved, quenched lattice QCD. At beta=6.2 on a 24^3x48 lat…
The Isgur-Wise Function from the Lattice
the UKQCD Collaboration
We calculate the Isgur-Wise function by measuring the elastic scattering amplitude of a meson in the quenched approximation on a lattice at , using an $O(…
Gauge-Invariant Smearing and Matrix Correlators using Wilson Fermions at beta=6.2
UKQCD Collaboration
We present an investigation of gauge-invariant smearing for Wilson fermions in quenched lattice QCD on a lattice at . We demonstrate a smearing algorithm t…
Non-Relativistic QCD for Heavy Quark Systems
S. Catterall, F. Devlin, I. Drummond +2
We employ a nonrelativistic version of QCD (NRQCD) to study heavy quark-antiquark bound states in the lowest approximation without fine structure. We use gluon configurations on a…
The Hyperfine Splitting in Charmonium: Lattice Computations Using the Wilson and Clover Fermion Actions
UKQCD Collaboration, C. R. Allton, C. T. Sachrajda +10
We compute the hyperfine splitting on the lattice, using both the Wilson and -improved (clover) actions for quenched quarks. The computations are performed…
Quenched Hadrons using Wilson and O(a)-Improved Fermion Actions at beta=6.2
The UKQCD Collaboration, C. R. Allton, H. Duong +20
We present the first study of the light hadron spectrum and decay constants for quenched QCD using an O(a)-improved nearest-neighbour Wilson fermion action at β=6.2. We compare the…
