Abstract

Using a sample of 2.59×107 ψ(2S) decays collected by the CLEO-c detector, we present results of a search for the decay chain ψ(2S)→π0hc, hc→n(π+π-)π0, n=1, 2, 3. We observe no significant signals for n=1 and n=3 and set upper limits for the corresponding decay rates. First evidence for the decay hc→π+π-π+π-π0 is presented, and a product branching fraction of B(ψ(2S)→hcπ0) ×B(hc→2(π+π-)π0)=1.88-0.45-0.30+0.48+0.47×10-5 is measured. This result implies that hc→hadrons and hc→γηc have comparable rates, in agreement with expectations.
