HIGGS BOSON RADIATION IN ELECTRON-POSITRON COLLISIONS

In this work discuss the process of the associated production of the Higgs boson H and a longitudinally polarized heavy fermion pair in the annihilation of an arbitrarily polarized electron-positron pair e(-)+e(+)->(gamma*; Z*)-> H + f + (f) over bar. The analytical expression of the differential cross section of the process is obtained, the features of the cross section behavior, the angular correlations of particles, the left-right spin asymmetry A(LR), the degree of longitudinal polarization of the fermion P-f, and the transverse spin asymmetry A(perpendicular to) are investigated. The results of the calculations are illustrated with graphs. The possibility of experimental measurement of the coupling constant g(Htt) is discussed.
