Report

Scaling behavior and positivity violation of the gluon propagator in full QCD

Autor: Bowman, Patrick O., Heller, Urs M., Leinweber, Derek B., Parappilly, Maria B., Sternbeck, Andre, von Smekal, Lorenz, Williams, Anthony G., Zhang, Jianbo

Publikováno v: Phys.Rev.D76:094505,2007

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 the nonperturbative infrared enhancement relative to the quenched cas

Report

Effects of dynamical sea-quarks on quark and gluon propagators

Autor: Parappilly, Maria B., Bowman, Patrick O., Heller, Urs M., Leinweber, Derek B, Williams, Anthony G., Zhang, J. B.

Publikováno v: AIP Conf.Proc.842:237-239,2006

We present an unquenched calculation of the quark propagator in Landau gauge with 2+1 flavors of dynamical quarks. We study the scaling behavior of the quark propagator in full QCD on two lattices with different lattice spacings and similar physical

Report

Scaling behavior of quark propagator in full QCD

Autor: Parappilly, Maria B., Bowman, Patrick O., Heller, Urs M., Leinweber, Derek B ., Williams, Anthony G., Zhang, J. B

Publikováno v: Phys.Rev.D73:054504,2006

We study the scaling behavior of the quark propagator on two lattices with similar physical volume in Landau gauge with 2+1 flavors of dynamical quarks in order to test whether we are close to the continuum limit for these lattices. We use configurat

Report

Unquenched quark propagator in Landau gauge

Autor: Bowman, Patrick O., Heller, Urs M., Leinweber, Derek B., Parappilly, Maria B., Williams, Anthony G., Zhang, Jianbo

Publikováno v: Phys.Rev.D71:054507,2005

We present an unquenched calculation of the quark propagator in Landau gauge with 2+1 flavors of dynamical quarks. We use configurations generated with an improved staggered (``Asqtad'') action by the MILC collaboration. This quark action has been se

Report

Unquenched Gluon Propagator in Landau Gauge

Autor: Bowman, Patrick O., Heller, Urs M., Leinweber, Derek B., Parappilly, Maria B., Williams, Anthony G.

Publikováno v: Phys.Rev.D70:034509,2004

Using lattice quantum chromodynamics (QCD) we perform an unquenched calculation of the gluon propagator in Landau gauge. We use configurations generated with the AsqTad quark action by the MILC collaboration for the dynamical quarks and compare the g
