摘要：
We use the method of light-cone sum rules to study the electromagnetic transition of the Xi(++)(cc) into Xi(++)(cc) gamma, whose decay width is estimated to be 13.7(-7.9)(+17.7) keV. This value is large enough for the Xi(cc)*(++) cthornthorn to be observed in the Xi(++)(cc) gamma channel, and we propose to continually search for it in future LHCb and BelleII experiments.
