Description

We study the 0++ glueball correlator constructed with SU(3) anisotropic quenched lattice QCD at various temperatures taking into account the possible existence of the thermal width in the ground-state peak. For this purpose, we adopt the Breit-Wigner ansatz, analysing the lattice data obtained with 5,500-9,900 gauge configurations at each T. The results indicate the significant thermal width broadening as Γ(Tc) ∼ 300 MeV with a reduction in the peak center as Δω0(Tc) ∼ 100 MeV in the vicinity of the critical temperature Tc. (author)
