| 英文摘要 | Using similar to 14 x 10(6)psi(2S) and similar to 58 x 10(6)J/psi data collected at BES II /BEPC, the branching fraction of psi(2S) -> Omega-(Omega) over bar (+) is measured with about 5 sigma statistical significance. The Lambda electric dipole and (A) over bar decay parameter are studied using the decay J/psi -> Lambda(Lambda) over bar -> p (p) over bar pi(+)pi(-). Using (106 +/- 3) x 10(6) psi(2S) decays collected at BESIII/BEPC II, we have obtained some interesting physics results. The branching fractions of chi(cJ) -> pi(0)pi(0), eta eta are measured with precision improved. The mass and width of h(c)(1(1)P(1)) state, together with the branching fractions of Br(psi(2S) -> pi(0)h(c)) and Br(h(c) -> gamma eta(c)) are the first measurements. Surprisingly, the decays of chi(c1) -> phi phi, omega omega, and omega phi are firstly observed in BESIII data. |
