Production of a Scalar Boson and a Fermion Pair in Arbitrarily Polarized e–e+ Beams

Аннотация

Within the framework of the Standard Model (Minimal Supersymmetric Standard Model) we consider the production of the scalar boson H_SM (h; H) and a fermion pair ff^– in arbitrarily polarized, counterpropagating electron-positron beams e ^– e ⁺ ⇒ H_SM (h; H) ff^–. Characteristic features of the behavior of the cross sections and polarization characteristics (right-left spin asymmetry, degree of longitudinal polarization of the fermion, and transverse spin asymmetry) are investigated and elucidated as functions of the energy of the electron-positron beams and the mass of the scalar boson.
