【 摘 要 】

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 κυ and κⅾ quarks. The parameters obtained using pseudoscalar density constant gℼ± , current masses of υ- and ⅾ-quarks as well as decay constant ℼ± → ℓ±νℓ were used for numerical modeling of Fℼ0γ(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.
