Abstract

We study hadron properties near the deconfining transition in the quenchedlattice QCD simulation. This gaper focuses on the heavy quarkonium states,such as J/psi meson. In order to treat heavy quarks at T > 0, we adopt theO(a) improved Wilson action on anisotropic lattice. We discuss c (c) over bar bound state observing the wave function and compare the mason correlators at above and below T-c. Although we find a large change of correlator near the T-c, the strong spatial correlation which is almost the same as confinement phase survives even T similar to 1.5T(c).
