Higgs masses and Electroweak Precision Observables in the Lepton-Flavor-Violating MSSM

Understand

We study the effects of Lepton Flavor Violation (LFV) in the scalar lepton sector of the MSSM on precision observables such as the W-boson mass and the effective weak leptonic mixing angle, and on the Higgs-boson mass predictions.

• The slepton mass matrices are parameterized in a model-independent way by a complete set of dimensionless parameters which we constrain through LFV decay processes and the precision observables.
• We find regions where both conditions are similarly constraining.
• The necessary prerequisites for the calculation have been added to FeynArts and FormCalc and are thus publicly available for further studies.
