Hadron Spectroscopy Tenth International Conference on Hadron Spectroscopy

The main topic of the conference was the physics of strong interaction and the understanding of how quarks form hadrons, which are part of the atomic nucleus. The proceedings give a comprehensive overview of the present status of the physics of hadrons. Topics include: mesons, baryons, scalars, exotics, heavy quarks, theoretical concepts, hadrons in matter, and reactions. The timing of the conference was very fortunate as many new and surprising results appeared in the months before its start. The highlights were the discussions about the nature of the recently discovered arrow states.
