χ_{c0,2} decay into light meson pairs and its implication of the scalar meson structures

Qiang Zhao

In light of the recent data from BES collaboration for ${\chi }_{c0}\to VV$, $PP$ and $SS$, and from CLEO-c for $\eta \eta$, ${\eta }^{\prime }{\eta }^{\prime }$ and $\eta {\eta }^{\prime }$, we present a detailed analysis o…
