Description

We consider the production of dilepton/photon in deconfined Quark Gluon Plasma (QGP). In the region of semi-QGP, effective color degrees of freedom are suppressed by a small value of the Polyakov loop. We find that the effect of the Polyakov loop leads to modest enhancement in the dilepton production rate but strong suppression in the photon production rate. The suppression of photon production in the QGP phase offers a possible explanation to the puzzle of photon elliptic flow
