摘      要：In 2012,we investigated the possible molecular states composed of two charmed mesons[***.D 88(2013)114008;2012 arXiv:1211.5007[hep-ph]].The D^(*)D𝐷system with the quantum numbers of I(J^(P))=0(1^(+))was found to be a good candidate of the loosely bound molecular *** state is very close to theD*D threshold with a binding energy around 0.47 *** prediction was confirmed by the new LHCb observation of𝑇T^(+)_(cc)[see Franz Muheim’s talk at the European Physical Society conference on high energy physics 2021].
