Abstract | Thermal properties of glueballs in SU(3) Yang-Mills theory are investigated in a large temperature range from 0.3T(c) to 1.9T(c) on anisotropic lattices. The glueball operators are optimized for the projection of the ground states by the variational method with a smearing scheme. Their thermal correlators are calculated in all 20 symmetry channels. It is found in all channels that the pole masses M(G) of glueballs remain almost constant when the temperature is approaching the critical temperature T(c) from below, and start to reduce gradually with the temperature going above T(c). The correlators in the 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) of each thermal glueball ground state. While the values of omega(0) are insensitive to T in the whole temperature range, the thermal widths Gamma exhibit distinct behaviors at temperatures below and above T(c). The widths are very small (approximately a few percent of omega(0) or even smaller) when T < T(c), but grow abruptly when T > T(c) and reach values of roughly Gamma similar to omega(0)/2 at T approximate to 1.9T(c). |
