| Abstract | Using anisotropic lattices glueballs at finite temperature are investigated in a large ternperature range from 0 3T(c) to 1 9T(c) in quenched lattice QCD where T-c is the critical temperature Optimized glueball operators are used in the calculations It is found that in all 20 symmetry channels the pole masses M-G of glueballs remain almost constants when the temperature approaches T-c from below and start to reduce gradually with the temperature going above T-c The glueball correlators in 0(++) 0(-+) and 2(++) channels are also analyzed based on the Breit-Wigner ansatz by assuming a thermal width Gamma to the pole mass omega(0) We found that while omega(0) s are insensitive to T in the whole temperature range, the Gamma s exhibit distinct behavior below and above T-c They are only a few percent of omega(0) when T < T-c but grow rapidly when T > T-c and reach values of roughly Gamma similar to omega(0)/2 at Gamma approximate to 1 9T(c), I 9Tc |
