Scalar Glueball Mass Reduction at Finite Temperature in SU(3) Anisotropic Lattice QCD

Abstract

We report the first study of the glueball properties at finite temperatures below T_c using SU(3) anisotropic lattice QCD with beta=6.25, the renormalized anisotropy xi \equiv a_s/a_t = 4 and 20^3 \times N_t (N_t=35,36,37,38,40,43,45,50,72) at the quenched level. From the temporal correlation analysis with the smearing method, about 20 % mass reduction is observed for the lowest scalar glueball as m_G(T)=1250 \pm 50MeV for 0.8 T_c < T < T_c in comparison with m_G \simeq 1500 \sim 1700MeV at T \simeq 0.

This is the second revised version using more gauge configurations. 5 pages, Latex2e, 5 figures
