Dilepton radiation in heavy-ion collisions at small transverse momentum

We study the invariant-mass distributions of dileptons produced in ultrarelativistic heavy-ion collisions at very low pair transverse momenta, PT≤0.15GeV. Specifically, we investigate the interplay of thermal radiation with initial photon annihilation processes, γγ→l+l−, triggered by the coherent el...
