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 m_top and m_bottom. We will describe our methods of calculation and renormalization as well as numerical evaluation of SUSY parameters.
