Jet-Quenching Parameter $hat{q}$ in the Nonperturbative Region
2016
New Physics Sae Mulli
We investigate the jet-quenching parameterq for the quark-gluon plasma (QGP) for Nc = 3, defined nonperturbatively with the Wilson loop in the light-cone (LC) coordinate, at finite temperature (T ). Considering the effective static (heavy) quark-antiquark potential VQ Q = σL + C − A/L, where L indicates the LC transverse separation between the quarks, we obtainq ≈ 8VQ Q /L 2 . The T dependences for L and other relevant parameters are extracted from the T -dependent instanton (trivial-holonomy
