Gluons in the lattice SU(2) classical field

High Energy Physics - Lattice 2017-08-23 v1

Abstract

The SU(2) gluonic correlation functions, glueball effective masses in the JP=0+J^{P}=0^{+}, 2+2^{+} and 00^{-} channels were calculated from the lattice classical gauge configurations which were obtained by smoothing the thermal gauge configurations through the improved cooling method. The instanton-induced attractive force in the 0+0^{+} channel and the repulsive force in the 00^- channel are confirmed in the Monte Carlo simulation. There is evidence that the instanton vacuum contribution to the 0+0^+ glueball mass is significant.
