Model dependent analyses on the $N_{c}$ dependence of the $σ$ pole trajectory

Z. X. Sun, L. Y. Xiao, Z. G. Xiao +1

We explore the nature of the $σ$ or $f_{0} (600)$ meson using large $N_{c}$ technique, assuming that the $σ$ pole dominates low energy physics in the IJ=00 channel. We trace the $N_{c}$ de…

On the nature of the lightest scalar resonances

Z. X. Sun, L. Y. Xiao, Z. G. Xiao +2

We briefly review the recent progresses in the new unitarization approach being developed by us. Especially we discuss the large $N_{c}$ $π π$ scatterings by making use of the partial…
