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…

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…

The decay $τ \to 3 π ν_{τ}$ and axial-vector meson $a_{1}$ in the NJL model

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

The branching fractions of $τ \to π^{+} π^{-} π^{-} ν_{τ}$ and $τ \to π^{-} 2 π^{0} ν_{τ}$ are calculated within the chiral NJL model. Features of the axial-vector $a_{1}$ meson which plays an importan…
