Abstract
We consider production of dilepton pairs through coherent. electromagnetic radiation during nuclear collisions. We show that the number of pairs produ ced through bremsstrahlung is about two orders of magnitude smaller than th e yield measured by the CERES Collaboration. Therefore, coherent bremsstrah lung can be ruled out as an explanation for the observed enhancement of low mass dileptons in CERES and HELIOS data. [S0556-2813(98)04012-6].
