The quark model was formulated in 1964 to classify mesons as bound states made of a
quark–antiquark pair, and baryons as bound states made of three quarks. For a long time all …

The nuclear-physics landscape has been redesigned as a sequence of effective field
theories (EFTs) connected to the standard model through symmetries and lattice simulations …

A coupled-channel approach is applied to the charged tetraquark state T cc+ recently
discovered by the LHCb Collaboration. The parameters of the interaction are fixed by a fit to …

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 …

Chiral symmetry and its spontaneous breaking play an important role both in the light
hadron and heavy hadron systems. The chiral perturbation theory (χ PT) is the low energy …

Multiquark resonances are undoubtedly experimentally observed. The number of states and
the amount of details on their properties have been growing over the years. It is very recent …

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

This review presents an overview of the remarkable progress in the field of heavy-quark
exotic hadrons over the past 15 years. It seeks to be pedagogical rather than exhaustive …

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 …
