Production of lepton pairs from an arbitrarily magnetised QCD medium

Abstract

We have estimated the rate of production of lepton pairs from a magnetised hot and dense QCD medium. We get rid of all kinds of previously considered approximations in terms of the strength of the magnetic field as well as the components of the momentum of the emitted lepton pairs. We find an enhancement in the rate in presence of an arbitrary strength of the magnetic field. With further consideration of an effective model scenario, we find the appearance of a gap in the rate. The implications of such a gap and other quasi-quark effects on the rate have been investigated in detail.
