Circular Polarization of a γ-Quantum in the Radiative Decay \( H\Rightarrow \overline{ff}\upgamma . \) Part I

  • Published:
Russian Physics Journal Aims and scope

The process of radiative decay of a Higgs boson into a fermion-antifermion pair \( H\Rightarrow \overline{ff}\upgamma . \) is investigated within the framework of the Standard Model. Taking into account the helicity of fermions and the circular polarization of a γ-quantum, an analytical expression for the decay width has been obtained. Circular polarization of the γ-quantum is examined in detail as a function of the angle θ and the invariant mass x of the fermion pair.
