Abstract
We extract the spectral functions in the scalar, pseudo-scalar, vector, and axial-vector channels above the deconfinement phase transition temperature ( T c ) using the maximum entropy method (MEM). We use anisotropic lattices, 32 3 × 32, 40, 54, 72, 80, and 96 (corresponding to T = 2.3 T c → 0.8T c ), with the renormalized anisotropy Σ = 4.0 to have enough temporal data points to carry out the MEM analysis. Our results suggests that the spectral functions continue to possess non-trivial structures even above T c and in addition that there is a qualitative change in the state of the deconfined matter between 1.5 T c and 2 T c .
