N2 - By analyzing (448.1±2.9)×106 ψ(3686) events collected with the BESIII detector operating at the BEPCII collider, the decays of χcJ→4KS0 (J=0, 1, 2) are observed for the first time with statistical significances of 26.5σ, 5.9σ and 11.4σ, respectively. The product branching fractions of ψ(3686)→γχcJ, χcJ→4KS0 are presented, and the branching fractions of χcJ→4KS0 decays are determined to be Bχc0→4KS0=(5.76±0.34±0.38)×10-4, Bχc1→4KS0=(0.35±0.09±0.03)×10-4 and Bχc2→4KS0=(1.14±0.15±0.08)×10-4, where the first uncertainties are statistical and the second are systematic, respectively.
