8 Sep 2003 | | Subject: | hep-ph hep-lat hep-th nucl-th | | Abstract: | In Landau gauge QCD the infrared behavior of the propagator of transverse gluons can be analytically determined to be a power law from Dyson-Schwinger equations. This propagator clearly shows positivity violation, indicating the absence of the transverse gluons from the physical spectrum, i.e. gluon confinement. A simple analytic structure for the gluon propagator is proposed capturing all important features. We provide arguments that the Landau gauge quark propagator possesses a singularity on the real timelike axis. For this propagator we find a positive definite Schwinger function. | | Source: | arXiv, hep-ph/0309078 | | Services: | Forum | Review | PDF | Favorites | |
