摘要
介绍了最近几年在BaBar,Belle,CDF,D0等实验室发现的新"奇特"强子以及国内外相关的理论研究情况。同时也介绍了作者所在课题组最近关于重味分子态,特别是X(3872),Y(4260)和Z+(4430)的研究进展。介绍了目前关于这些"奇特"强子态研究的困难和不足,指出了未来可能的研究方向。
Many new hadron states were observed by the BaBar, Belle, CDF, DO 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.
