Searches for isospin-violating transitions χc0,2 → π0ηc

We present the first upper-limit measurement of the branching fractions of the isospin-violating transitions χc0,2→π0ηc. The measurements are performed using 106×106 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...
