Abstract

We study exclusive χc0,1,2 decays to four-hadron final states involving two charged and two neutral hadrons: π+π-π0π0, K+K-π0π0, pp̄π0π0, K+K-ηπ0, and K± n K0 n 0. The χc states are produced in radiative decays of 3.08×106 ψ(2S) resonance decays and observed in the CLEO detector. We also measure the largest substructure contributions to the modes π+π-π0π0 and K± K0π0.
