Özet
The decays chi(cJ) -> Sigma(0)(p) over barK(+) + c.c. (J = 0,1,2) are studied via the radiative transition psi(3686) ->gamma chi(cJ) based on a data sample of (448.1 +/- 2.9) x 10(6) psi(3686) events collected with the BESIII detector. The branching fractions of chi(cJ) -> Sigma(0)(p) over barK(+) + c.c. (J = 0,1,2) are measured to be (3.03 +/- 0.12 +/- 0.15) x 10(-4), (1.46 +/- 0.07 +/- 0.07) x 10(-4), and (0.91 +/- 0.06 +/- 0.05) x 10(-4), respectively, where the first uncertainties are statistical and the second are systematic. In addition, no evident structure is found for excited baryon resonances on the two-body subsystems with the limited statistics.
