Hadron and Quarkmonium Exotica

Abstract: A number of charmonium-(bottmonium-)like states have been observed in $B$-factory experiments. Recently the BESIII experiment has joined this search with a unique data sample collected at the different center of mass energies ranging from 3.9 GeV to 4.42 GeV in which they found new charmonium-like states with non-zero electric charge. We review the status of experimental searchs for quarkomonium-like states and also other types of non-$q\bar{q}$ meson or non-$qqq$ baryons that are predicted by QCD-motivated models. We mainly focus on results from the $B$-factories and BESIII.
