Two-Loop Corrections to the Muon Magnetic Moment from Fermion/Sfermion Loops in the MSSM — •Christoph Gnendiger — Institut für Kern- und Teilchenphysik, TU Dresden

In this talk we present two-loop corrections to the muon (g-2) from fermion/sfermion loops in the MSSM. These corrections are generally large and even logarithmically enhanced for heavy sfermions. Details of the calculation are presented and a very compact formula is provided which serves as a good approximation of the full result. The discussion of the numerical behaviour includes the case of very heavy SUSY masses as well as experimentally allowed scenarios with very light SUSY masses.
