摘要: We study the radiative decays of the Zc(3900)0 in a hadronic molecule picture, where the Zc(3900) is treated as a DD¯∗+c.c hadronic molecule. The partial widths of Γ(Zc(3900)0→γηc(2S)) and Γ(Zc(3900)0→γχc0) are predicted to be of order 10 keV and the cross sections for σ(e+e−→π0Zc(3900)→π0γηc(2S)) and σ(e+e−→π0Zc(3900)→π0γχc0) are of order 0.1 pb at 4.23 GeV, which may be accessible for the BESIII and forthcoming BelleII.
