| 英文摘要 | The detection efficiency corrections for the particle identification and kinematic fit selection criteria are investigated for the branching fraction measurements in psi' decays into omegapi(+) pi(-), b(1)pi, omegaf(2), (1270), omegak(+) k-, omegap (p) over bar, phipi(+) pi(-), phif(0)(980), phik(+) k-, phip (p) over bar final states using 4 x 10(6) psi' data sample collected at bepc/bes. based on the corrected efficiencies, the preliminary results of these decay channels have been obtained, and the "12 %" rule predicted by perturbative qcd theory has been tested. |
