Abstract / Full Text

Within the framework of the Standard Model, the channel of the Higgs boson radiative decay into a fermion-antifermion pair \( \mathrm{H}\mathbf{\Rightarrow}\mathrm{f}\overline{\mathrm{f}\upgamma} \) is investigated. Taking into account the fermion and W-boson loop diagrams, an analytical expression for the decay width is obtained, and the circular γ-quantum polarization is studied depending on the angle θ and the invariant mass of the fermion pair.
