$1/ N_{c}$ approximation and universality of vector mesons

M. K. Volkov, A. A. Osipov, A. A. Pivovarov +1

In this work, we argue that the observed differences in the value of the vector coupling constant extracted from the decays $ρ \to π π$ ( $g_{ρ} = 6.0$ ), $ρ \to l^{+} l^{-}$ ( $g_{ρ} = 5.0$ ) an…

The possibility to use the width of the decay $ρ \to e^{+} e^{-}$ to fix the input parameter $g_{ρ} = 5.0$ of the $S U (2) \times S U (2)$ chiral-symmetric Nambu--Jona-Lasinio model is discu…

On the mixing angle of the vector mesons $ω (782)$ and $ϕ (1020)$

M. K. Volkov, A. A. Pivovarov, K. Nurlan

In the present work, the mixing angle of the vector $ω (782)$ and $ϕ (1020)$ mesons is estimated in the framework of Nambu--Jona-Lasinio model. The decay $ϕ \to π^{0} γ$ is considered…

The decay $τ \to K^{* 0} (892) K^{-} ν_{τ}$ in the extended NJL model

M. K. Volkov, A. A. Pivovarov, K. Nurlan

In the extended Nambu -- Jona-Lasinio model, the decay width of $τ \to K^{* 0} (892) K^{-} ν_{τ}$ is calculated. The contributions from the contact diagram and diagrams with intermediate…

The decay $τ \to K^{*-} (892) η ν_{τ}$ in the NJL model

M. K. Volkov, A. A. Pivovarov, K. Nurlan

The decay width $τ \to K^{*-} (892) η ν_{τ}$ was calculated in the Nambu--Jona-Lasinio model. Four channels were taken into account: the contact channel (the final states are directly p…

The decays $τ \to [ω (782), ϕ (1020)] K^{-} ν_{τ}$ in the extended NJL model

M. K. Volkov, A. A. Pivovarov, K. Nurlan

In the extended Nambu--Jona-Lasinio model, the decay widths of the processes $τ \to [ω (782), ϕ (1020)] K^{-} ν_{τ}$ were calculated. The intermediate channels with axial vector ($K_{1}…
