MEM Analysis of Glueball Correlators at T>0
Noriyoshi Ishii, Hideo Suganuma
Abstract
Maximum Entropy Method (MEM) is applied to glueball correlators at finite temperature constructed by using 5,500-9,900 gauge field configurations generated in SU(3) quenched lattice QCD with the lattice parameter beta = 2Nc/g2 = 6.25 and the renormalized anisotropy as/at = 4. The results support the thermal width broadening of the 0++ glueball near the critical temperature.
