Decays $τ \to f_{0} (π, K) ν_{τ}$ and $τ \to 3 π ν_{τ}$ accounting for the contribution of $f_{0} (500)$

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

In the $U (3) \times U (3)$ quark NJL model, $τ$ lepton decays with the production of scalar mesons $f_{0} (π, K])$ and neutrinos are studied, where $f_{0} = f_{0} (500), f_{0} (980)$ . It is shown…

Weak semileptonic decays of vector mesons in the NJL model

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

The decay widths of $V \to K (π) l ν ˉ_{l}$ are calculated within the Nambu--Jona-Lasinio model, where $V = K^{*}, ρ, ω, ϕ$ and $l = μ, e$ . The results are obtained using the previously…

Description of the processes $e^{+} e^{-} \to π^{+} π^{-}$ and $τ^{-} \to π^{-} π^{0} ν_{τ}$ in the NJL model with value of the vector coupling constant $g_{ρ} = 6$

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

It is shown that the processes $e^{+} e^{-} \to π^{+} π^{-}$ and $τ^{-} \to π^{-} π^{0} ν_{τ}$ can be described in a unified approach in satisfactory agreement with experiment using the vector cou…

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

In the framework of the $U (3) \times U (3)$ extended Nambu-Jona-Lasinio model, the processes $e^{+} e^{-} \to K^{+} K^{-} π^{0}$ and $e^{+} e^{-} \to K^{+} K^{-} η$ are described taking into account both g…
