Dalitz decays of unflavored mesons in the Poincare covariant quark model

Abstract

The procedure for obtaining the radiative decay constants of pseudoscalar and vector unflavored mesons in the point-form of PiQM is presented. Based on the obtained earlier parameters of the model for light (𝑢, 𝑑, 𝑠) quarks, we obtain the remaining parameters from the experiments on the 𝑉 → 𝑃𝛾 and 𝑃 → 𝑉 𝛾 decays. As a result, the mixing angles for pseudoscalar and vector mesons and the behavior of the 𝑉 → 𝑃ℓ+ℓ− decay constant are obtained in agreement with modern experimental data.
