χc0,2 decay into light meson pairs and its implication of the scalar meson structures

In light of the recent data from BES collaboration for χc0 → V V , PP and SS, and from CLEO-c for ηη, η′η′ and ηη′, we present a detailed analysis of the decays of heavy quarkonia into light meson pairs such as χc0,2 → V V , PP and SS in a recently proposed parametrization scheme. An overall agreement with the data is achieved in χc0,2 → V V and PP , while in χc0 → SS we find that a possible existence of glueball-qq̄ mixings is correlated with the OZI-rule violations, which can be further examined at CLEO-c and BESIII in χc0 → SS measurement.
