Unitary chiral dynamics in J/Psi -> VPP decays and the role of scalar mesons
TLDR
In this paper, the authors make a theoretical study of the J/psi decays into omegapipi, phipipi and omegaK over bar using the techniques of the chiral unitary approach stressing the importance of the scalar resonances dynamically generated through the final state interaction of the two pseudoscalar mesons.About:

From controversy to precision on the sigma meson: a review on the status of the non-ordinary $f_0(500)$ resonance
TL;DR: The sigma meson has been controversial for almost six decades, despite playing a central role in the spontaneous chiral symmetry of QCD or in the nucleon-nucleon attraction as discussed by the authors.

Chiral Perturbation Theory: Expansions in the Mass of the Strange Quark
Jürg Gasser,Heinrich Leutwyler +1 more
TL;DR: In this paper, the authors construct the generating functional of U(3)×U(3), which allows them to calculate the Green functions up to and including terms of order p4 (at fixed radio m quark p 2 ) in terms of a few coupling constants which chiral symmetry leaves undetermined.
