Center vortices and the quark propagator in SU(2) gauge theory
Patrick O. Bowman, Kurt Langfeld, Derek B. Leinweber +4
We study the behavior of the AsqTad quark propagator in Landau gauge on quenched SU(2) gauge configurations under the removal of center vortices. In contrast to recent results in S…
A Numerical Approach to Coulomb Gauge QCD
Hrayr H. Matevosyan, Adam P. Szczepaniak, Patrick O. Bowman
We calculate the ghost two-point function in Coulomb gauge QCD with a simple model vacuum gluon wavefunction using Monte Carlo integration. This approach extends the previous analy…
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…
Scaling behavior and positivity violation of the gluon propagator in full QCD
Patrick O. Bowman, Urs M. Heller, Derek B. Leinweber +5
The Landau-gauge gluon propagator is studied using the coarse and fine dynamical MILC configurations. The effects of dynamical quarks are clearly visible and lead to a reduction of…
