N2 - Based on (2.712±0.014)×109 ψ(3686) events collected by the BESIII Collaboration, evidence of the hadronic decay hc→KS0K+π-+c.c. is found with a significance of 4.3σ in the ψ(3686)→π0hc process. The branching fraction of hc→KS0K+π-+c.c. is measured to be (7.3±1.8±0.8)×10-4, where the first and second uncertainties are statistical and systematic, respectively. Combining with the exclusive decay width of ηc→KK̄π, our result indicates inconsistencies with both pQCD and NRQCD predictions.
