Gauge-covariant diagonalization of $π$ - $a_{1}$ mixing and the resolution of a low energy theorem

A. A. Osipov, M. M. Khalifa, B. Hiller

Using a recently proposed gauge covariant diagonalization of $π a_{1}$ -mixing we show that the low energy theorem $F^{π} = e f_{π}^{2} F^{3 π}$ of current algebra, relating the anomalous form…

Decay rates $f_{1} (1285) \to ρ^{0} π^{+} π^{-}$ and $a_{1} (1260) \to ω π^{+} π^{-}$ in the Nambu -- Jona-Lasinio model

A. A. Osipov, A. A. Pivovarov, M. K. Volkov

The anomalous decays $f_{1} (1285) \to ρ^{0} π^{+} π^{-}$ and $a_{1} (1260) \to ω π^{+} π^{-}$ violating natural parity for vectors and axial-vectors are studied in the framework of the Nambu -- Jona-Lasi…

Nonuniform phases in the 't Hooft extended Nambu--Jona-Lasinio Model

J. Moreira, B. Hiller, A. A. Osipov +1

The phase diagram of cold dense quark matter is studied using the 't Hooft extended Nambu--Jona-Lasinio Model applied to the light quark sector with a finite current mass for the s…

Non-uniform phases in a three-flavour 't Hooft extended Nambu-Jona--Lasinio model

J. Moreira, B. Hiller, W. Broniowski +2

The possible existence of non-uniform phases in cold dense quark matter in the light quark sector ( $u$ , $d$ and $s$ ) is addressed using the Nambu-Jona--Lasinio Model extended to in…

The $T - μ$ phase diagram of the NJL model in the presence of explicit symmetry-breaking interactions

J. Morais, J. Moreira, B. Hiller +2

It is shown that the strange quark mass undergoes a first order transition in a generalized 3 flavor Nambu--Jona-Lasinio (NJL) Lagrangian which includes a complete set of explicit…

The 3 flavor NJL with explicit symmetry breaking interactions: scalar and pseudoscalar spectra and decays

A. A. Osipov, B. Hiller, A. H. Blin

The effective quark interactions that break explicitly the chiral SU(3)_L X SU(3)_R and U_A(1) symmetries by current-quark mass source terms are considered in NLO in $N_{c}$ counting…
