Wave Functions of the Proton Ground State in the Presence of a Uniform Background Magnetic Field in Lattice QCD
Dale S. Roberts, Patrick O. Bowman, Waseem Kamleh +1
We calculate the probability distributions of quarks in the ground state of the proton, and how they are affected in the presence of a constant background magnetic field. We focus…
Role of center vortices in chiral symmetry breaking in SU(3) gauge theory
Patrick O. Bowman, Kurt Langfeld, Derek B. Leinweber +3
We study the behavior of the AsqTad quark propagator in Landau gauge on SU(3) Yang-Mills gauge configurations under the removal of center vortices. In SU(2) gauge theory, center vo…
Impact of stout-link smearing in lattice fermion actions
Peter J. Moran, Patrick O. Bowman, Derek B. Leinweber +2
The impact of stout-link smearing in lattice fermion actions is examined through the consideration of the mass and renormalization functions of the overlap quark propagator over a…
Stout-link smearing in lattice fermion actions
J. B. Zhang, Peter J. Moran, Patrick O. Bowman +2
The properties of the momentum space quark propagator in Landau gauge are studied for the overlap quark action in quenched lattice QCD. Numerical calculations are performed over fo…
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…
