e+e- pair production in ultrarelativistic heavy-ion collisions at intermediate impact parameters

Abstract

Using the quasiclassical Green's function in the Coulomb field, we analyze the probabilities of single and multiple $e^{+}{e}^{-}$-pair production at fixed impact parameter $b$ between colliding ultrarelativistic heavy nuclei. We perform calculations in the Born approximation with respect to the parameter $Z_B\alpha$, and exactly in $Z_A\alpha$, $Z_A$ and $Z_B$ are the charge numbers of the corresponding nuclei. We also obtain the approximate formulas for the probabilities valid for $Z_A\alpha ,Z_B\alpha \lesssim 1$.
