Study of spatial meson correlators at finite temperature in quenched anisotropic lattice QCD
Abstract
We analyze the meson correlator in the spatial direction at finite temperature. To achieve fine resolution in the spatial direction, we use an anisotropic lattice with the standard Wilson plaquette gauge action and the O(a) improved Wilson quark action. Below and above Tc, properties of correlators are investigated by two methods: fits with ansatz for the spectral function, and direct reconstruction of the spectral function using the maximum entropy method.
