Associated Production of a Higgs Boson and Heavy Fermion Pair in e−e+-Collisions

Abstract

This article presents the results of studies of the associated production of the Higgs boson and a heavy fermion pair in arbitrarily polarized electron-positron collisions: \({e^ - }{e^ + } \to {H_{{\rm{SM}}}}f \bar{f}\), \({e^ - }{e^ + } \to Hf \bar{f}\), \({e^ - }{e^ + } \to hf \bar{f}\), and \({e^ - }{e^ + } \to Af \bar{f}\). Analytical expressions for the differential cross sections of the processes are obtained, the specific features of the behavior of the cross sections, angular and spin asymmetries are investigated depending on the energies and angles of emission of particles.
