Polarization properties of γ-quanta in 𝐻⇒𝑓+𝑓 ̅+Ɣ decaying		  pdf 

ABSTRACT

We have analyzed the Higgs-boson decaying process of 𝐻⇒𝑓+𝑓 ̅+γ based on the Feynman diagram. While considering the helicity of fermion-antifermion and the linear (circular) polarization , the cross-section of the 𝐻⇒𝑓+𝑓‾+γ in the framework of the standard model (SM) has been calculated. The linear or the circular polarization of the γ-quanta has been evaluated and the dependency of the fermion-antifermion pair over the x i.e. the invariant mass and the exiting θ angle has been investigated. The value for the linear and circular polarization of the γ-quanta during the 𝐻⇒τ-+τ++γ has been shown.

Keywords: Higgs Boson, Standard Model, γ-quanta polarization, Scattering matrix, Electroweak interaction, tau leptons.
