Abstract

Within the framework of the Minimal Supersymmetric Standard Model, the production of three Higgs bosons AhH in the reaction e^-e⁺ ⇢ AhH with arbitrary polarization of electron-positron beams is studied. Analytical expressions for the amplitude and differential effective cross section of the process are obtained. The left-right (A_LR) and transverse (A_φ) spin asymmetries, caused by the longitudinal and transverse spin states of the electron-positron pair, respectively, are calculated. A detailed analysis of the behavior of the spin asymmetries and the differential effective cross section as functions of the emission angles and energies of the final particles is performed. It is established that the left-right asymmetry A_LR is determined solely by the value of the Weinberg parameter x_W = sin²θw, while the transverse spin asymmetry A_φ is a complex function of the emission angles (θ_A, θ₁, θ₂) and scaling energies (x_A, x₁, x₂) of the Higgs bosons. The possibility of experimentally determining the constants of three-boson interactions: λ_Hhh, λ_HHh, λ_HAA and λ_hAA is discussed.
