Low momentum propagators at two loops in gluon mass model
arXiv:1409.0455 · doi:10.1088/1751-8113/47/44/445401
Abstract
We compute the two loop corrections to the gluon propagator for low momentum in a gluon mass model. This model has recently been proposed as an alternative to the Gribov construction in the way it handles Gribov copies in the gauge fixing. The corrections provide improvements for estimating the point where the gluon propagator freezes in relation to lattice data.
