英文摘要	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 psi(1(3)D(2)). Because the X(3823) is just near the D D* threshold, the decay X(3823) -> J/psi pi(+)pi(-) can be a golden channel to test the significance of coupled-channel effects. In this work, this decay is considered including both the hidden-charm dipion and the usual quantum chromodynamics multipole expansion (QCDME) contributions. The partial decay width, the dipion invariant mass spectrum distribution d Gamma[X(3823) -> J/psi pi(+)pi(-) ]/dm(pi+pi-), and the corresponding dG[X(3823) -> J/psi pi(+)pi(-) ]/d cos theta distribution are computed. Many parameters are determined from existing experimental data, so the results depend mainly only on one unknown phase between the QCDME and hidden-charm dipion amplitudes.
