Production of a Scalar Boson and a Heavy Fermion Pair in Counterpropagating Е^–Е⁺ Beams

The process of production of an HSM scalar boson of the Standard Model (H and h bosons of the Minimal Supersymmetric Standard Model) and a heavy fermion pair $t\overline{t}$ in counterpropagating electron-positron beams $e^{-}{e}^{+}\Rightarrow H_{SM}t\overline{t}(e^{-}{e}^{+}\Rightarrow Ht\overline{t};e^{-}{e}^{+}\Rightarrow ht\overline{t})$) is discussed. Analytical expressions for the energy spectrum of the Higgs boson and the transverse spin asymmetry and the right-left spin asymmetry are obtained, and their dependences on the emission angle and energy of the Higgs boson are investigated.
