The Charged Higgs Boson Mass of the MSSM in the Feynman-Diagrammatic Approach

Understand

The interpretation of the Higgs signal at \sim 126 GeV within the Minimal Supersymmetric Standard Model (MSSM) depends crucially on the predicted properties of the other Higgs states of the model, as the mass of the charged Higgs boson, MH+-.

• This mass is calculated in the Feynman-diagrammatic approach within the MSSM with real parameters.
• The result includes the complete one-loop contributions and the two-loop contributions of O(alpha_t alpha_s).
• The one-loop contributions lead to sizable shifts in the MH+- prediction, reaching up to \sim 8 GeV for relatively small values of M_A.
