The past decades witnessed the golden era of hadron physics. Many excited open heavy
flavor mesons and baryons have been observed since 2017. We shall provide an updated …

The past seventeen years have witnessed tremendous progress on the experimental and
theoretical explorations of the multiquark states. The hidden-charm and hidden-bottom …

Conventional, hadronic matter consists of baryons and mesons made of three quarks and a
quark–antiquark pair, respectively,. Here, we report the observation of a hadronic state …

Quantum chromodynamics, the theory of the strong force, describes interactions of coloured
quarks and gluons and the formation of hadronic matter. Conventional hadronic matter …

A large number of experimental discoveries especially in the heavy quarkonium sector that
did not meet the expectations of the until then very successful quark model led to a …

We discuss the phase structure of QCD for N f= 2 and N f= 2+ 1 dynamical quark flavors at
finite temperature and baryon chemical potential. It emerges dynamically from the …

The spectrum of hadrons is the manifestation of color confinement of quantum
chromodynamics. Hadronic resonances correspond to poles of the S-matrix. Since 2003 …

In the past decade many charmonium-like states were observed experimentally. Especially
those charged charmonium-like Z c states and bottomonium-like Z b states cannot be …

The inspiration for this book came from François le Diberder. During his term as
spokesperson for B 八 B 八 R he laid down a vision for the two B Factory detector …

Why do we see certain types of strongly interacting elementary particles and not others?
This question was posed more than 50 years ago in the context of the quark model. M. Gell …
