Abstract:

We present the first physics results for quenched QCD and for pure SU(2) gauge theory from the UKQCD collaboration. We report preliminary results for static quark potentials, the string tension and the quenched hadron spectrum on a 243 × 48 lattice at β = 6.2 using the standard Wilson fermion action and an O(a) improved nearest-neighbour Wilson fermion action. Our codes run at in excess of 1.5 Gflops in the 64-node Meiko i860-based Computing Surface at Edinburgh. We have also simulated pure gauge SU(2) theory on a 483 × 56 lattice at β = 2.85 to explore the approach to the continuum limit. © 1992.
