XYZ radiative transitions at BESIII

Many unexpected charmonium-like states have recently been observed above the $D\bar{D}$ threshold, which features can’t be explained by the conventional quark models. These states are known as XYZ mesons. The study of the radiative transition among these states can provide the important features of XYZ states. This study has recently been performed by the BESIII using the large data samples collected at different center-of-mass energies above 3.8 GeV. This report summarizes the recent results of XYZ radiative transitions at BESIII.
