研究目的
To discuss the process of production of a scalar boson (H or h) and a heavy fermion pair (tt) in counterpropagating electron-positron beams, obtain analytical expressions for the energy spectrum, transverse spin asymmetry, and right-left spin asymmetry, and investigate their dependences on the emission angle and energy of the Higgs boson.
研究成果
Analytical expressions for differential cross sections, transverse spin asymmetry, and left-right spin asymmetry were obtained. The dependences on emission angle and energy of the Higgs boson were investigated and illustrated graphically. The transverse spin asymmetry is negative and varies with angle and energy, while the cross section increases with energy. Differences between SM and MSSM processes were noted due to additional factors in the MSSM.
研究不足
The study is theoretical and does not involve experimental validation. It relies on specific models (SM and MSSM) and assumes certain parameters (e.g., particle masses, Weinberg parameter). The approximations made for high energies (s >= 1 TeV) may not hold for lower energies.
