    "abstract": "We present a calculation of higher order effects for the impact parameter\ndependent probability for single and multiple electron-positron pairs in\n(peripheral) relativistic heavy ion collisions. Also total cross sections are\ngiven for SPS and RHIC energies. We make use of the expression derived recently\nby several groups where the summation of all higher orders can be done\nanalytically in the high energy limit. An astonishing result is that the cross\nsection, that is, integrating over all impact parameters, is found to be\nidentical to the lowest-order Born result for symmetric collisions. For the\nprobability itself on the other hand we find rather large effects at small\nimpact parameters compared to the lowest order results, which translate to\nlarge effects for the cross section for multiple pair production.",
