Chiral anomaly in the η ( ′ ) → π + π − γ and η ( ′ ) → π + π − l + l − decays

M. K. Volkov, A. A. Osipov, K. Nurlan, А. А. Пивоваров

We report the presence of a flavor-violating correction to the V A A A -type anomaly, δ ( ′ ) , induced by the surface terms of the anomalous quark triangle diagram, previously found in the η , η ′ → π …

Decays τ → ππην τ and τ → πηην τ in the extended Nambu–Jona-Lasinio model

M. K. Volkov, А. А. Pivovarov, K. Nurlan

In the framework of the extended Nambu–Jona-Lasinio model, the processes τ → ππη(η′)ντ and τ → πηη(η′)ντ are considered taking into account mesons in the ground and first radially excited intermediate states. It is shown that in the processes τ → ππη(η′)ντ …

Decays $τ\to f_0(π,K) ν_τ$ and $τ\to 3 πν_τ$ 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 that these decays mainly occur via contact channels and channels with axial-vector mesons $a_1$, …
