One of the most important topics in nowadays light meson spectroscopy is to look for the particle states beyond quark model , including glueballs, hybrids etc. especially exotic states. The theoretical prediction for mass of 0~(-+), 2~(++) glueballs is from 2.1 GeV to 2.4 GeV , which is just within the energy region of Crystal Barrel experiment with very high statistics data on the pp annihilation in flight. To search for glueballs, we can take some lessons from chaimonium decay and radiative de
