Dissipative potential induced by QCD at finite temperature and density

In the framework of QCD at finite temperature, we have obtained dissipative factors for the effective potential between [Formula Presented] and [Formula Presented] which would partly explain the [Formula Presented] suppression in the quark gluon plasma (QGP). The derivation of the dissipative potential in the QGP is presented and the case in the hadron matter (HM) is briefly discussed. The suppression effects are numerically estimated based on simple approximations and a comparison with that caused by the Debye screening mechanism is also presented.
