| dc.description | The analysis of the poles of the $ππ$ scattering amplitude is shown to favour a dynamical origin of the sigma meson: it is created by a strongly attractive $ππ$ interaction in the $J^{PC}=0^{++}I=0$ channel. In the limit $N_c\to\infty$, the $σ$ meson disappears, contrary to the case of conventional $q\bar{q}$ states. Implications for the search of the scalar $q\bar{q}$ and glueball states are discussed. | |
