Spin 3/2 Pentaquark Resonance Signature in Lattice QCD
B. G. Lasscock, D. B. Leinweber, W. Melnitchouk +4
The possible discovery of the Theta+ pentaquark has motivated a number of studies of its nature using lattice QCD. While all the analyses thus far have focussed on spin-1/2 states,…
Spin-3/2 Baryons in Lattice QCD
J. M. Zanotti, S. Choe, D. B. Leinweber +3
We present first results for masses of spin-3/2 baryons in lattice QCD, using a novel fat-link clover fermion action in which only the irrelevant operators are constructed using fa…
Excited Baryons from the FLIC Fermion Action
W. Melnitchouk, J. N. Hedditch, D. B. Leinweber +3
Masses of positive and negative parity excited nucleons and hyperons are calculated in quenched lattice QCD using an O(a^2) improved gluon action and a fat-link clover fermion acti…
Light Quark Simulations With FLIC Fermions
J. M. Zanotti, D. B. Leinweber, W. Melnitchouk +2
Hadron masses are calculated in quenched lattice QCD in order to probe the scaling behavior of a novel fat-link clover fermion action in which only the irrelevant operators of the…
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…
