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.

The “Physics in Collision” conference aims to provide an overview of the main topics of high energy physics. This annual international meeting consists of three days of exclusive review talks, given by invited speakers. As a result, it has taken on a unique character, ideal for those who wish to be brought up to date on the current status of particle physics.

This book presents a comprehensive overview of high energy physics. It covers the whole range of results from the colliders and fixed-target experiments as well as the astrophysics topics related to particle physics. Also discussed are the problems of proton structure, electroweak physics, non-perturbative QCD and heavy quarks.
