Selected oblique two-loop corrections to (g−2)µ in the MSSM — •Marco Schäfer, Dominik Stöckinger, Hyejung Stöckinger-Kim, and Philipp von Weitershausen — Institut für Kern- und Teilchenphysik, 01062 Dresden

We have calculated selected two-loop diagrams contributing to the muon anomalous magnetic moment in the Minimal Supersymmetric Standard Model. These are chargino or neutralino one-loop diagrams with an additional third generation squark or squark-quark loop. Such diagrams exhibit oblique corrections as in the Standard Model and typically contain mtop and mbottom. We will describe our methods of calculation and renormalization as well as numerical evaluation of SUSY parameters.
