Gauge Corrections to Leptogenesis II — •Frederik Depta, Andreas Halsch, and Owe Philipsen — Institut für Theoretische Physik, Goethe-Universität Frankfurt, Max-von-Laue-Str. 1, 60438 Frankfurt am Main, Germany

We discuss a systematic calculation of gauge corrections to leptogenesis, which requires resummations for a consistent and complete evaluation of the leading order contribution in the framework of Kadanoff-Baym equations. The resulting lepton number matrix includes all leading order Standard Model gauge corrections. It consists of a multidimensional integral over solutions of partial differential equations. We present prospects for its numerical solution.
