Description

K*(892)0K*(892)0 signals from χcJ(J=0,1,2) decays are observed for the first time using a data sample of 14 million ψ(2S) events accumulated in the BES II detector. The branching fractions B[χcJ→K*(892)0K*(892)0] (J=0,1,2) are determined to be (1.78±0.34±0.34)x10-3 (1.67±0.32±0.31)x10-3, and (4.86±0.56±0.88)x10-3 for the χc0, χc1, and χc2 decays, respectively, where the first errors are statistical and the second are systematic. The significances of these signals are about 4.7σ, 4.5σ, and 7.6σ, respectively
