英文摘要 | Using a data sample of 106 million psi(3686) events collected with the besiii detector operated at the bepcii storage ring, we study for the first time the decays chi(cj) -> phi(ksk +/-)-k-0 pi(-/+) and chi(cj) -> phi k+k-pi(0) in the e1 radiative transition psi(3686) -> gamma chi(cj). the decays are dominated by the three-body decay chi(cj) -> phi k*(892)(k) over bar. we measure branching fractions for this reaction via the neutral and charged k*(892) and find them consistent with each other within the expectation of isospin symmetry. in the k (k) over bar pi invariant mass distribution, a structure near the k*(892)(k) over bar mass threshold is observed, and the corresponding mass and width are measured to be 1412 +/- 4(stat) +/- 8(sys) mev/c(2) and gamma = 84 +/- 12(stat) +/- 40(sys) mev, respectively. the observed state favors an assignment to the h(1)(1380), considering its possible j(pc) and comparing its mass, width and decay mode to those reported in the particle data group. |
