报告摘要:
The quark model has been applied very successfully in describing the
mesons and baryons and their properties. It is known that all the established mesons
are made of a quark and an antiquark, while baryons are composed of three
quarks. In principle, hadrons composed with more than three valence quarks are
not prohibited by the fundamental theory of strong interactions, namely the
so-called QCD. In this talk I"ll examine the status of the multi-quark hadrons,
including tetraquark mesons, pentquark baryons and hexaquark mesons. We also
explain why the quark model often encounters a great challenge in understanding
scalar mesons.
