Centre Vortices in SU(3)
Alan Ó Cais, Waseem Kamleh, Kurt Langfeld +3
We investigate the effectiveness of using smearing as a means to generate a preconditioning transformation for gauge fields prior to fixing to Maximal Centre Gauge. This still leav…
Scaling analysis of FLIC fermion actions
Waseem Kamleh, Ben Lasscock, Derek B. Leinweber +1
The Fat Link Irrelevant Clover (FLIC) fermion action is a variant of the -improved Wilson action where the irrelevant operators are constructed using smeared links. While the…
Unquenching effects in the quark and gluon propagator
Waseem Kamleh, Patrick O. Bowman, Derek B. Leinweber +2
In this work we examine the Fat-Link Irrelevant Clover (FLIC) overlap quark propagator and the gluon propagator on both dynamical and quenched lattices. The tadpole-improved Lusche…
Even parity excitations of the nucleon in lattice QCD
B. G. Lasscock, J. N. Hedditch, W. Kamleh +4
We study the spectrum of the even parity excitations of the nucleon in quenched lattice QCD. We extend our earlier analysis by including an expanded basis of nucleon interpolating…
Pseudoscalar and vector meson form factors from lattice QCD
J. N. Hedditch, W. Kamleh, B. G. Lasscock +3
We present a study of the pseudoscalar and vector meson form factors, calculated using the Fat-Link Irrelevant Clover (FLIC) action in the framework of Quenched Lattice QCD. Of par…
Signature Changing Space-times and the New Generalised Functions
Waseem Kamleh
A signature changing spacetime is one where an initially Riemannian manifold with Euclidean signature evolves into the Lorentzian universe we see today. This concept is motivated b…
