Title: Multiquark state and mixing of scalar meson

Keywords: quark model, multiquark, mixing of scalar meson

Abstract:
The mixing of scalar meson is still an open problem. In order to describe KN scattering process in a chiral quark model, the mixing of σ_0 and σ_8 scalar mesons must be considered.  Now we present the results of multiquark states with and without the mixing of scalar meson in a chiral quark model by solving the resonating group method equation
