| Abstract: |
We study hadron properties near the deconfining transition in the quenched lattice QCD simulation. This paper focuses on the heavy quarkonium states, such as J/ψ meson. In order to treat heavy quarks at T > 0, we adopt the O(a) improved Wilson action on anisotropic lattice. We discuss c&cmacr; bound state observing the wave function and compare the meson correlators at above and below T[sub c]. Although we find a large change of correlator near the T[sub c], the strong spatial correlation which is almost the same as confinement phase survives even T ∼ 1.5T[sub c]. [ABSTRACT FROM AUTHOR] |
