Using large Nc counting rule, it is argued that tetra-quark resonances do not exist. Also it is pointed out that there exists the violation of exchange degeneracy in the exotic KN scattering channel. It implies either the failure of resonance saturation assumption or it suggests the existence of exotic baryon resonances in such a channel.

S Matrix

By studying ππ scattering amplitudes in the large-N c limit, we clarify the N c dependence of the S matrix pole position. It is demonstrated that analyticity and the N c counting rule exclude the existence of S-matrix poles with [Formula: see text]. Especially the properties of σ and f0(980) with respect to the 1/N c expansion are discussed. We point out that in general tetra-quark resonances do not exist.

Baryon Resonances

Identifying a zero-range exchange of vector mesons as the driving force for the s-wave scattering of pseudo-scalar mesons off the baryon ground states, a rich spectrum of hadronic nuclei is formed. We argue that chiral symmetry and large-Nc considerations determine that part of the interaction which generates the spectrum. We suggest the existence of strongly bound crypto-exotic baryons, which contain a charm-anti-charm pair. Such states are narrow since they can decay only via OZI-violating processes.
