Abstract:We present the first upper-limit measurement of the branching fractions of the isospin-violating transitions χc0,2 → π 0 ηc. The measurements are performed using 106 × 10 6 ψ(3686) events accumulated with the BESIII detector at the BEPCII e + e − collider at a center-of-mass energy corresponding to the ψ(3686) mass. We obtained upper limits on the branching fractions at a 90% confidence level of B(χc0 → π 0 ηc) < 1.6 × 10 −3 and B(χc2 → π 0 ηc) < 3.2 × 10 −3 .
