The determination of alpha_s(M_z) from perturbative analyses of short-distance-sensitive lattice QCD observables revisited
K. Maltman, D. Leinweber, P. Moran +1
The determination of alpha_s(M_Z) via perturbative analyses of short-distance-sensitive lattice observables is revisited, incorporating new lattice data and performing a modified v…
Chiral extrapolation of octet-baryon charge radii
P. Wang, D. B. Leinweber, A. W. Thomas +1
The charge radii of octet-baryons obtained in quenched lattice-QCD calculations are extrapolated within heavy-baryon chiral perturbation theory. Finite-range regularization (FRR) i…
The Realistic Lattice Determination of alpha_s(M_Z) Revisited
K. Maltman, D. Leinweber, P. Moran +1
We revisit the earlier determination of alpha_s(M_Z) via perturbative analyses of short-distance-sensitive lattice observables, incorporating new lattice data and performing a modi…
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…
