Calculation of the width of the decay $τ \to K^{-} K^{0} ν_{τ}$ in the extended NJL model with estimation of the contribution of the kaon final state interaction

M. K. Volkov, A. A. Pivovarov

The branching fraction of the decay $τ \to K^{-} K^{0} ν_{τ}$ is calculated in the framework of the extended Nambu--Jona-Lasinio model. The contact and vector channels are considered.…

The second-class current decays $τ \to π η (η^{'}) ν_{τ}$ in the NJL model including the interaction of mesons in the final state

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

The effect of the interaction of mesons in the final state is additionally considered within the description of $τ \to π η (η^{'}) ν_{τ}$ decays. This interaction is taken into account at…

The decay $τ \to K^{-} η ν_{τ}$ in the extended Nambu-Jona-Lasinio model taking into account the meson interaction in the final state

M. K. Volkov, A. A. Pivovarov

The branching fraction of the decay $τ \to K^{-} η ν_{τ}$ has been calculated by using the extended Nambu-Jona-Lasinio model taking into account the meson interaction in the final stat…

$1/ N_{c}$ 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…
