===== Description=====
This Topical Group will address experimental and theoretical aspects concerning

  * precision studies of properties of heavy mesons and baryons
  * exotic heavy or light hadronic states (tetraquarks, pentaquarks, hybrids, glueballs)
  * related theory

The goal is to identify the priorities and challenges and establish a roadmap for the next decades, from ongoing and planned experiments to future colliders/facilities.

===== Subgroups=====
There are three subgroups, closely collaborating with each other, each with several sub-conveners representing various experimental and theoretical communities:
