摘要

In the past decade, an amount of the so-called XYZ particles were found in the facilities around the world, such as Belle, BABAR and BESIII. It is difficult to put these particles into the conventional framework of quark model,so attracts physicists’ special attention. An interesting observation is that many of the XYZ particles are near the threshold of two charmed mesons.
