Description

In this article [1], we have explored the very important quantity of lepton pair production from a hot and dense QCD medium in presence of an arbitrary magnetic field for simultaneous nonzero values of both the parallel and perpendicular components of momentum. As opposed to the zero magnetic field case (the so-called Born rate) or the lowest Landau level approximated rate, where only the annihilation process contributes, here we observe contributions also arising out of the quark and antiquark decay processes. We found the encouraging result of considerable enhancement of lepton pair production in presence of a magnetic field. We further decompose the total rate into different physical processes and make interesting observations for both zero and nonzero baryon density. The whole analysis is then subjected to an effective model treatment, which leads us to some further interesting observations.
