THE PRODUCTION OF CP-ODD HIGGS BOSONS IN POLARIZED ELECTRON-POSITRON COLLISIONS

Within the framework of the Minimal Supersymmetric Standard Model (MSSM), taking into account arbitrary polarization states of the electron-positron pair, analytical expressions of differential effective cross sections of the processes of the production of three CP-odd Higgs bosons and a Z-boson, and two CP-odd Higgs bosons in electron-positron collisions are obtained: e −e + → AAA, e −e + → ZAA. All possible Feyman diagrams with vertices ZΦA, ZAA and ZZΦ, ΦAA, ZZAA, ZΦA, ΦZA are taken into account, where Φ− CP-even Higgs boson – h or H. Left-right (ALR) and transverse (Aϕ) spin asymmetries are determined, characteristic features of the behavior of asymmetries and differential effective cross-sections of processes depending on the departure angles and particle energies are investigated. It is shown that the left-right asymmetry ALR depends only on the Weinberg parameter xW = sin2 θW , and the transverse spin asymmetry Aϕ is a function of the departure angles and the particle energy. The possibility of measuring the three-boson interaction constant λΦAA and the gZZAA constant of the interaction of two Z-bosons and two A-bosons is discussed.
