MEM analysis of glueball correlators at T > 0
Abstract
Maximum Entropy Method (MEM) is applied to glueball correlators at finite temperature constructed by using 5,5009,900 gauge field configurations generated in SU(3) quenched lattice QCD with the lattice parameter β_{lat} = 2 N_{c}/ g^{2} = 6.25 and the renormalized anisotropy {a _{s}}/{a _{t}} = 4 . The results support the thermal width broadening of the 0 ^{++} glueball near the critical temperature.
