Abstract
Based on 14M ψ′ events collected by BESII detector, the decays of χcJ into the final states π+π-K+K-, [Formula: see text], 2(K+K-), [Formula: see text], ηπ+π- and [Formula: see text] are studied. The branching fractions of these decays or intermediate states involved are reported. These results shed light on the understanding of scalar meson properties and the χcJ decay mechanisms.
