Abstract

Using the maximum entropy method (MEM), we extract the spectral functions in the scalar, pseudo-scalar, vector, and axial-vector channels above the deconfinement phase transition temperature ( T c ). Our result suggests that the spectral functions continue to possess non-trivial structures even above T c . Also, there is a qualitative change in the state of the deconfined matter between 1.5 T c and 2 T c .
