Description
Recently the LHCb Collaboration announced the discovery of a new type of
exotic hadron -- a doubly-charmed tetraquark $T_{cc}^+$, whose mass agrees
precisely with a 2017 theoretical prediction. I will discuss the recent
related experimental and theoretical developments regarding new types of
hadrons: tetraquark and pentaquark hadronic molecules, doubly heavy baryons,
stable tetraquarks and others.
