The decay $\tau \to 3\pi\nu_\tau$ and axial-vector meson $a_1$ in the NJL model
Autor: K., Volkov M., K., Nurlan, A, Pivovarov A.
The branching fractions of $\tau \to \pi^+ \pi^-\pi^- \nu_\tau$ and $\tau \to \pi^- 2\pi^0\nu_\tau$ are calculated within the chiral NJL model. Features of the axial-vector $a_1$ meson which plays an important role in describing the $\tau$ decays are

The decay $τ\to 3πν_τ$ and axial-vector meson $a_1$ in the NJL model
Autor: K., Volkov M., K., Nurlan, A, Pivovarov A.
The branching fractions of $τ\to π^+ π^-π^- ν_τ$ and $τ\to π^- 2π^0ν_τ$ are calculated within the chiral NJL model. Features of the axial-vector $a_1$ meson which plays an important role in describing the $τ$ decays are discussed. Permiss

Calculation of doubly heavy baryons decay
Autor: K. Nurlan, Zh.Zh. Tyulemissov, A.K. Bekbaev, D.T. Aznabaev, Aidos Issadykov
Publikováno v: Recent Contributions to Physics. 78:4-11
We calculated a subclass of four nonleptonic two-body weak decays of the double charm baryon ground states Ξcc++. Nonleptonic decays can be dividedinto two group: factorizable and nonfactorizable decays. The first one can be easily calculated from f

The decays η′→ πρ and ρ → πη in the chiral NJL model
Autor: M. K. Volkov, A. A. Pivovarov, K. Nurlan
Publikováno v: Modern Physics Letters A. 37
The branching fractions of the decays [Formula: see text] and [Formula: see text] are calculated in the chiral quark NJL model. The decays exist due to the mass difference between [Formula: see text]- and [Formula: see text]-quarks leading to [Formul

Semileptonic Decays of Vector Mesons $$[\rho ,\omega ,\phi ] \to \pi [{{e}^{ + }}{{e}^{ - }},{{\mu }^{ + }}{{\mu }^{ - }}]$$ in a Chiral NJL Model
Autor: M. K. Volkov, K. Nurlan
Publikováno v: Physics of Particles and Nuclei Letters. 18:148-152
Semileptonic decays of vector mesons $$\rho $$ , $$\omega $$ , ϕ into a pion and lepton pair $${{e}^{ + }}{{e}^{ - }},{{\mu }^{ + }}{{\mu }^{ - }}$$ are described in the chiral Nambu–Jona–Lasinio (NJL) model. Mixing of $$\omega $$ with ϕ is tak
