Abstract

In the course of work the integral representation of ℼ⁰-meson form-factor of ℼ⁰ → γγ process has been obtained within relativistic quark model based on point form of Poincaré-invariant quantum mechanics taking into account anomalous magnetic moments of κ_υ and κ_ⅾ quarks. The parameters obtained using pseudoscalar density constant g_ℼ± , current masses of υ- and ⅾ-quarks as well as decay constant ℼ^± → ℓ^±_νℓ were used for numerical modeling of F_ℼ0γ(t) form-factor in time-like region. Similar calculations for ℼ⁰ → γγ decay characteristics with reference to quark structure in point form of Poincaré-invariant quantum mechanics have been carried out for the first time.
