Di-Quarks and Tri-Quarks on the Lattice
A. I. Signal, F. R. P. Bissey, D. B. Leinweber
The distribution of gluon fields in hadrons is of fundamental interest in QCD. Using lattice QCD we have observed the formation of gluon flux tubes within tri-quark (baryon) system…
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…
Buried treasure in the sand of the QCD vacuum
P. J. Moran, D. B. Leinweber
The short-range structure of the 2+1 flavour QCD vacuum is studied through visualisations of the topological charge density. Of particular interest is a new Gaussian weighted smear…
Over-Improved Stout-Link Smearing
Peter J. Moran, Derek B. Leinweber
A new over-improved stout-link smearing algorithm, designed to stabilise instanton-like objects, is presented. A method for quantifying the selection of the over-improvement parame…
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…
Aspects of QCD Vacuum Structure
Peter J. Moran, Derek B. Leinweber
The impact of dynamical fermions on the vacuum structure of QCD is explored. Of particular interest is the topological charge correlator, , where negative values at s…
