Coulomb corrections and multiple e+e--pair production in ultrarelativistic nuclear collisions
An attempt was made to demonstrate that the difference in the definitions of the exclusive cross section σ1 and the inclusive cross section σT cannot lead to the cancellation of the Coulomb corrections in the latter. Using the proper regularization of the expression for σT, a result was obtained for the Coulomb corrections that in the limiting case ZAα≪1 agrees with that obtained in the Weizsäcker-Williams approximation.
