摘要：

We study exclusive chi(c0,1,2) decays to four-hadron final states involving two charged and two neutral hadrons: pi(+)pi(-)pi(0)pi(0), K+K-pi(0)pi(0), p (p) over bar pi(0)pi(0), K+K-eta pi(0) and K-+/-pi K--/+(0)pi(0). The chi(c) states are produced in radiative decays of 3.08 x 10(6) psi(2S) resonance decays and observed in the CLEO detector. We also measure the largest substructure contributions to the modes pi(+)pi(-)pi(0)pi(0) and K-+/-pi K--/+(0)pi(0).
