Abstract
Although quantum chromodynamics, the theory of strong interaction, allows new forms of matter such as hadronic molecule, multi-quark states, hybrids and glueballs to exist in nature, experimental evidences for the candidates of those particles have appeared only about a decade ago. Such forms of matter go by the name of exotica since their quark content is distinct from the conventional baryons (e.g., protons) and mesons. So-called XYZ particles, good candidates for exotica, have been mostly discovered at the \(e^{+}e^{-}\) flavor factories namely Belle and BaBar. The candidates of pentaquarks have been recently observed by the LHCb experiment at CERN. This talk will review these states, which are of great interest to the field of hadron spectroscopy.
