Probing the phases in the MSSM via e^+ e^- \to h A

Abstract

In the presence of the supersymmetric CP phases, e^+ e^- \to Z^{*} \to h A scattering is analyzed, with special emphasis on Z^{*} h A vertex, taking into account radiatve corrections due to dominant top quark and top squark loops in the Higgs sector as well as the vertex formfactors. It is found that the lightest Higgs remains essentially CP-even whereas the heavier ones mix with each other strongly. Moreover, the supersymmetric CP phases are found to create tree-level couplings between a pseudoscalar and identical sfermion mass eigenstates which, together with the radiative corrections in the Higgs sector, are found to enhance the vertex formfactors significantly.
