CP asymmetries in charged Higgs boson decays in MSSM

Abstract

In the Standard Model with Minimal Supersymmetry, the Lagrangian contains complex parameters which lead to additional CP violation. We study CP violating asymmetries in the decays of the MSSM charged Higgs boson, induced by loop corrections with intermediate SUSY particles, and perform analytical and numerical analysis. The decay rate asymmetry can go up to 25% and the forward-backward asymmetry can reach up to 10%.
