Mass of scalar resonances beyond the large- $N_{c}$ limit

Christophe Bruno, Elisabetta Pallante

Within the Extended Nambu Jona-Lasinio model we analyse the $1/ N_{c}$ -corrections to the leading order result $M_{S} = 2 M_{Q}$ where $M_{Q}$ is the constituent quark mass.

$γ γ \to π^{0} π^{0}$ and $η \to π^{0} γ γ$ at low energy within the Extended Nambu Jona-Lasinio Model

S. Bellucci, C. Bruno

Within the Extended Nambu Jona-Lasinio model, we calculate the $O (p^{6})$ counterterms entering the low-energy expansion of the $γ γ \to π^{0} π^{0}$ and the $η \to π^{0} γ γ$ amplitudes in Ch…

Rare Kaon Decays in the $1/ N_{c}$ -Expansion

C. Bruno, J. Prades

We study the unknown coupling constants that appear at order $p^{4}$ in the Chiral Perturbation Theory analysis of $K \to π γ^{*} \to π l^{+} l^{-}$ , $K^{+-} \to π^{+-} γ γ$ and $K \to π π γ$ d…

Nambu Jona-Lasinio Like Models and the Low Energy Effective Action of QCD

Johan Bijnens, Christophe Bruno, Eduardo de Rafael

We present a derivation of the low energy effective action of an extended Nambu Jona-Lasinio (ENJL) model to $O (p^{4})$ in the chiral counting. Two alternative scenarios are consider…
