Query: Way to Discriminate between Mesons and Glueballs for $I=0,
  J^{PC}=even^{++}$ Unflavored Hadrons   Based on the general analysis of branching ratio of two pseudoscalar meson
channels, discriminants between mesons and glueballs for $I=0,
J^{PC}=even^{++}$ unflavored hadrons with mass between 1.2 GeV and 2.9 GeV are
suggested. Known $I=0, J^{PC}=2^{++}, f_2(1525)$ particle is discriminated as a
typical meson. The way to discriminate new $I=0, J^{PC}=even^{++}$ unflavored
hadrons is discussed.
