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…
