Towards the Continuum Limit of the Overlap Quark Propagator in Landau Gauge
J. B. Zhang, F. D. R. Bonnet, P. O. Bowman +2
The properties of the momentum space quark propagator in Landau gauge are examined for the overlap quark action in quenched lattice QCD. Numerical calculations were done on two lat…
Quark propagator in a covariant gauge
F. D. R. Bonnet, D. B. Leinweber, A. G. Williams +2
Using mean--field improved gauge field configurations, we compare the results obtained for the quark propagator from Wilson fermions and Overlap fermions on a $\3$ lattice at a spa…
Excited Baryons in Lattice QCD
W. Melnitchouk, S. Bilson-Thompson, F. D. R. Bonnet +5
We present first results for the masses of positive and negative parity excited baryons calculated in lattice QCD using an O(a^2)-improved gluon action and a fat-link irrelevant cl…
Overlap Quark Propagator in Landau Gauge
Frédéric D. R. Bonnet, Patrick O. Bowman, Derek B. Leinweber +2
The properties of the quark propagator in Landau gauge in quenched QCD are examined for the overlap quark action. The overlap quark action satisfies the Ginsparg-Wilson relation an…
Baryon resonances from a novel fat-link fermion action
W. Melnitchouk, S. Bilson-Thompson, F. D. R. Bonnet +6
We present first results for masses of positive and negative parity excited baryons in lattice QCD using an O(a^2) improved gluon action and a Fat Link Irrelevant Clover (FLIC) fer…
Novel fat-link fermion actions
J. M. Zanotti, S. Bilson-Thompson, F. D. R. Bonnet +6
The hadron mass spectrum is calculated in lattice QCD using a novel fat-link clover fermion action in which only the irrelevant operators of the fermion action are constructed usin…
