摘要

Very recently, the Belle and BESIII experiments observed a new charmonium-like state X(3823), which is a good candidate for the D-wave charmonium (13D2). Because the X(3823) is just near the DˉD threshold, the decay X(3823) ! J= +?? can be a golden channel to test the significance of coupled-channel effects. In this work[1], this decay is considered including both the hidden-charm dipion and the usual quantum chromodynamics multipole expansion (QCDME) contributions.
