Physical Review D, 86(7).1550-79981550-2368https://doi.org/10.1103/PhysRevD.86.072011https://journals.aps.org/prd/abstract/10.1103/PhysRevD.86.072011http://hdl.handle.net/11452/29252Using (106 +/- 4) x 10(6) psi ' events accumulated with the BESIII detector at the BEPCII e(+)e(-) collider, we present measurements of the branching fractions for psi' decays to K+K- pi(0) and K+K- eta. In these final states, the decay psi' -> K-2(*) (1430)(+) K- + 10(-5), is observed for the first time, and its branching fraction is measured to be (7.12 +/- 0: 62(stat)(-0.61)(+1.13) (syst)) x 10(-5), which indicates a violation of the helicity selection rule in psi' decays. The branching fractions of psi' -> K* (892)(+) K- + c.c., phi eta, and phi pi(0) are also measured. The measurements are used to test the QCD predictions on charmonium decays.eninfo:eu-repo/semantics/openAccessAstronomy & astrophysicsPhysicsExperimental study of psi ' decays to K+K- pi(0) and K+K-etaArticle0003102604000032-s2.0-84868028195867Astronomy & astrophysicsPhysics, particles & fieldsCharmonium; Drift Chambers; Branching
