Chiral nonet mixing in $$\pi \eta $$ π η scattering
Abstract The generalized linear sigma model for mixing among two- and four-quark components of scalar (and pseudoscalar) mesons below and above 1 GeV is applied to the $$\pi \eta $$ π η channel in which the isovector scalars $$a_0(980)$$ a 0 ( 980 ) and $$a_0(1450)$$ a 0 ( 1450 ) are probed. In the...
