Based on the general analysis of decay width and branching ratio of two pseudo scalar meson channels, two sets of discriminants between mesons and glueballs for1 = 0,J ^PC = even⁺⁺ unflavored hadrons with the mass between 1.2 and 2.9 GeV are suggested. Known1 = 0,J ^PC = 2⁺⁺, f₂(1525) particle is discriminated as a typical meson. The way to discriminate new1 = 0,J ^PC = even⁺⁺ unflavored hadrons is discussed.
