摘要
Although tetraquarks and pentaquarks[1]were predicted along with the quark model in 1964,more than half a century passed,multiquark-like states observed in experiments are still rare.Among these states,the structure of hardly any was identified;whether they are multiquarks,molecules of hadrons,or other possible species of resonances are still under debate(for a review,see e.g.,Refs.[2,3]).
