    "abstract": "We perform a gauge-transformation on the time-dependent Dirac equation\ndescribing the evolution of an electron in a heavy-ion collision to remove the\nexplicit dependence on the long-range part of the interaction. We solve, in an\nultra-relativistic limit, the gauged-transformed Dirac equation using\nlight-front variables and a light-fronts representation, obtaining\nnon-perturbative results for the free pair-creation amplitudes in the collider\nframe. Our result reproduces the result of second-order perturbation theory in\nthe small charge limit while non-perturbative effects arise for realistic\ncharges of the ions.",
