Pionic Decay of ρ±-Meson in Relativistic Quantum Mechanics Theory

The integral representation of ρ± ⟶ π±π0 decay constant has been obtained in relativistic quantum mechanics based on point form of dynamics. It is shown that soft pion theorem usage in the proposed approach leads to numerical results consistent with modern experimental data. As a result a self-consistent model for light π±-, ρ±-meson observed electroweak and pionic characteristic calculation is proposed.
