| 英文摘要 | We report measurements of branching fractions for psi(2S) decays into omegapi(+)pi(-), b(1)pi, omegaf(2)(1270), omegaK(+)K(-), omegap (p) over bar, phipi(+)pi(-), phif(0)(980), phiK(+)K(-), and an upper limit for phip (p) over bar final states based on a data sample of (4.02+/-0.22)x10(6)psi(2S) events collected with the BESI detector at the Beijing Electron-Positron Collider. The branching fractions for b(1)pi and omegaf(2)(1270) update previous BES results, while those for other decay modes are first measurements. The ratios of psi(2S) and J/psi branching fractions are smaller than what is expected from the 12% rule by a factor of 5 for omegaf(2)(1270) and by a factor of 2 for omegapi(+)pi(-), omegap (p) over bar, and phiK(+)K(-), while for other studied channels the ratios are consistent with expectations within errors. |
