Isolating the Roper Resonance in Lattice QCD
M. S. Mahbub, Alan Ò Cais, Waseem Kamleh +3
We present results for the first positive parity excited state of the nucleon, namely, the Roper resonance (=1440 MeV) from a variational analysis technique. The ana…
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…
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…
exotic meson at light quark masses
J. N. Hedditch, W. Kamleh, B. G. Lasscock +3
The mass of the exotic meson, created with hybrid interpolating fields, is explored at light quark masses approaching 25 MeV (). Access to such light q…
