英文摘要 | Measurement of the production cross section of the D-s(+) D-s(-) in e(+) e(-) annihilation at the Center-of-Mass Energy of roots = 4.03 GeV is reported in the paper. The cross section for the D: DI production has been measured using a data sample of 22.3 pb(-1) collected with BES detector at BEPC e(+) e(-) collider. The D-s(+) measons are reconstructed in the phi pi (+), (K*(0)) over barK(+) and (K-0) over barK(+) decay modes. A total number of 94 +/- 13 singly tagged D-s(+) events is obtained from the three modes. This yelds the cross section value sigmaD(s)(prod+)D(s)(-) = (451 +/- 63 +/- 118)pb for D-s(+) D-s(-) production. Based on the numbers of singly tagged D-s(+) events for each of the three decay modes,the decay branching fractions for D-s(+) --> (K*(0)) over barK(+) and (K-0) over barK(+) have been determined to be (3.02 +/- 0.94 +/- 0.91)% and (3.28 +/- 1.22 +/- 0.94)%, respectively. |
