• We recently observed the iso-singlet scalar σ(600)-particle and the iso-doublet scalar κ(900)-particle, through the re-analyses of ππ- and Kπ-scattering phase shifts, respectively. First, assuming the two iso-singlet states, the σ(600) and the established f_0(980), being the ideal mixing states nn^^- and ss^^-, respectively, of a single scalar nonet, it is pointed out that the mass value of the iso-singlet flavor-octet state, obtained from the orthogonal transformation, satisfies, together with the κ(900) and the iso-triplet scalar a_0(980)-particle, the Gell-Mann Okubo mass-formula. Furthermore, it is argued that, by investigating their properties of masses and widths, this scalar σ-nonet, together with the pseudo-scalar π-nonet, realizes the linear representation of SU(3) chiral symmetry.
