| 英文摘要 | The process e(+)e(-) -> d*d-+(s)*(s0) (2317)(-) + c.c. is observed for the first time with the data sample of 567 pb(-1) collected with the besiii detector operating at the bepcii collider at a center-of-mass energy root s = 4.6 gev. the statistical significance of the d*(s0) (2317)(+/-) signal is 5.8 sigma and the mass is measured to be (2318.3 +/- 1.2 +/- 1.2) mev/c(2). the absolute branching fraction b(d*(s0) (2317)(+/-) -> pi d-0(s)+/-) is measured as 1.00(-0.14)(+0.00) (stat)(-0.14)(+0.00) (syst) for the first time. the uncertainties are statistical and systematic, respectively. |
