报告简介：

The fundamental theory of strong interaction, quantum chromodynamics

(QCD), is nonperturbative at low energies. Thus, it is still a challenge

to understand the structure of hadrons which are composed of quarks and

gluons. There are two kinds of hadrons: mesons and baryons. Most of them

can be well described in a quark model with a meson consisting of a pair

of quark and antiquark and a baryon consisting of three quarks. In

addition, exotic hadrons beyond these configurations are expected to

exist as well, such as glueballs, hybrids, multiquark states and

hadronic molecules. However, strong evidence for the exotic hadrons only

appeared recently due to worldwide experimental efforts. To identify the

nature of QCD exotica from the data is one of the most challenging

problems of hadron physics, and needs well-devised theoretical tools

such as lattice QCD and effective field theories. In this talk, I will

focus on one kind of QCD exotica --- hadronic molecules. Using a few

examples, I will show how they can be identified and that such a goal

should be achieved with joint efforts of experimentalists and theorists.
