Gluon Propagators in QCD.
Abstract
Two currently interesting problems in QCD that tie with gluon propagation are studied here. (1) At finite temperatures, the gluon propagator develops masses from theoretical fluctuations in the infrared limit. We reexamine a recent calculation of the magnetic mass m(,mag) in the temporal gauge and show that there is not necessary a g('3)T('2) term in. (DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI). (2) Recent studies of the infrared behavior of the propagator in the infrared limit suggest a momentum singularity of 1/q('4) behavior for the gluon propagator which corresponds to a linear quarkantiquark potential. Lattice calculations however show an approximate 1/q('2) (instead of 1/q('4)) behavior. There is thus a discrepancy between the continum limit analytical and numerical lattice calculations.
