摘要：

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 xiequivalent toa(s)/a(t)=4 and 20(3)xN(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+/-50 MeV for 0.8T(c)<T<T-c in comparison with m(G)similar or equal to1500-1700 MeV at Tsimilar or equal to0.
