Comment on the absence of Coulomb effects on $e^{+}{e}^{-}$ pair production in ultrarelativistic heavy-ion collisions

D. Yu. Ivanov, A. Schiller, V. G. Serbo

In recent works [Segev,Wells; Baltz, McLerran; Eichmann, Reinhardt, Schramm, Greiner] it was claimed that the Coulomb correction to the $e^{+}{e}^{-}$ production cross section in relativ…
