| 英文摘要 | Based on a sample of 58 X 10(6) J/psi decays collected with the BESII detector at the BEPC, the (Lambda) over bar decay parameter alpha((Lambda) over bar) for (Lambda) over bar -> (p) over bar pi(+) is measured using about 9000 J/psi -> Lambda(Lambda) over bar -> p (p) over bar pi(+)pi(-) decays. A fit to the joint angular distributions yields alpha((Lambda) over bar) ((Lambda) over bar -> (p) over bar pi(+)) = -0.755 +/- 0: 083 +/- 0: 063, where the first error is statistical, and the second systematic. |
