The decays χ cJ → Σ 0p K þ þ c:c: ðJ ¼ 0; 1; 2Þ are studied via the radiative transition ψð3686Þ → γχ cJ based on a data sample of ð448.1 AE 2.9Þ × 10 6 ψð3686Þ events collected with the BESIII detector. The branching fractions of χ cJ → Σ 0p K þ þ c:c: ðJ ¼ 0; 1; 2Þ are measured to be ð3.03 AE 0.12 AE 0.15Þ × 10 −4 ,
