✦ Synopsis
Reanalyzing the-S-wave (TrTr)i=0 and (KTr)I=l/2 phase shifts through a new S-matrix parametrization method, the existence of a(600) and n(900)-particles is suggested, respectively. These particles have plausible properties as the members of scalar nonet, appeared as partners of pseudoscalar 7r-nonet in linear representation of chiral symmetry. The properties of the other members of a-nonet, 6(I = 1) and a'(s~), are also predicted by SU(3) linear a model(LaM). The negative background phase, introduced phenomenologically, has some correspondence to the Af4-interaction in LaM. Our relevant scalar-particles, "Chiralons," should be discriminated from those in the conventional qq 3p0-states.
