Measurement of B(ψ (3770) → γχc1) and search for ψ (3770) → γχc2

We report a measurement of the branching fraction for ψ(3770)→γχc1 and search for the transition ψ(3770)→γχc2 based on 2.92  fb−1 of e+e− data accumulated at s√=3.773  GeV with the BESIII detector at the BEPCII collider. We measure B(ψ(3770)→γχc1)=(2.48±0.15±0.23)×10−3, which is the most precise mea...
