The σ(600) and κ(900), observed in the phase shift analyses [1,2], satisfy rather well the mass and width relation predicted by the SU(3)LσM and the SU(3)LσM with the vector and axial-vector meson nonets, and deserve to be the members of scalar σ-nonet, together with the observed resonances and as a chiral partner of pseudoscalar π-nonet. In the phase shift analyses an introduction of repulsive background phase is essential, whose origin has a close connection to the interaction in LσM. It is argued that the members of this σ-nonet, “Chiralons,” have different properties and should be discriminated from the conventional -scalar nonet.
