Decays $f_{1} \to a_{0} π, π π π (η)$ and $f_{1} \to K K π$ in the chiral $U (3) \times U (3)$ quark NJL model

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

The branching fractions of the axial vector meson decays $f_{1} \to a_{0} π, π π η$ , $f_{1} \to ρ π, π π π$ and $f_{1} \to K K π$ are calculated in the standard $U (3) \times U (3)$ quark NJL model.…

Decays $τ \to π π η ν_{τ}$ and $τ \to π η η ν_{τ}$ in the extended Nambu-Jona-Lasinio model

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

In the framework of the extended Nambu-Jona-Lasinio model, the processes $τ \to π π η (η^{'}) ν_{τ}$ and $τ \to π η η (η^{'}) ν_{τ}$ are considered taking into account mesons in the ground and first r…

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…
