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

Аннотация

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 \( {e}^{-}{e}^{+}\Rightarrow {H}_{\mathrm{SM}}t\overline{t}\left({e}^{-}{e}^{+}\Rightarrow Ht\overline{t};{e}^{-}{e}^{+}\Rightarrow ht\overline{t}\right) \)) 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.
