| Abstract: | Many new hadron states were observed by the BaBar,Belle,CDF,D0 collaborations in recent years,some of which did not fit into the quark model easily.We reviewed our group's systematic work on the heavy molecular states especially X(3872),Y(4260) and Z +(4430) and discussed the difficulties and challenges in this field and the possible improvement in the future. |
