Abstract

Using 14 million ψ(2S) events collected with the BESII detector, branching fractions of ψ(2S)→K*(892)⁺K ^-+c.c. and K*(892)⁰K̄⁰+c.c. are determined to be: B(ψ(2S)→K*(892)⁺K ^-+c.c.)=(2.9_-1.7^+1.3±0.4)×10 ^-5 and B(ψ(2S)→K*(892) ⁰K̄⁰+c.c.)=(13.3_-2.7 ^+2.4±1.7)×10-5. The results confirm the violation of the "12% rule" for these two decay channels. A large isospin violation between the charged and neutral modes is observed.

N2 - Using 14 million ψ(2S) events collected with the BESII detector, branching fractions of ψ(2S)→K*(892)+K -+c.c. and K*(892)0K̄0+c.c. are determined to be: B(ψ(2S)→K*(892)+K -+c.c.)=(2.9-1.7+1.3±0.4)×10 -5 and B(ψ(2S)→K*(892) 0K̄0+c.c.)=(13.3-2.7 +2.4±1.7)×10-5. The results confirm the violation of the "12% rule" for these two decay channels. A large isospin violation between the charged and neutral modes is observed.
