| 英文摘要 | Using 14 million ψ(2S) events collected with the BESII detector, branching fractions of ψ(2S) → K-*(892)+K- +c.c. and K-*(892)(0)(K) over bar (0) + c.c. are determined to be: B(ψ(2S) → K-*(892)K-+(-) + c.c.) = (2.9(-1.7)(+1.3) ± 0.4) x 10(-5) and B(ψ (2S) K-*(892)(0)(K) over bar (0)+ c.c.) = (13.3(-2.7)(+2.4) ± 1.7) x 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. © 2005 Published by Elsevier B.V. |
