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

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 …

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 cross section for the process e+ e-→ π+ π-J/ψ is measured precisely at center-of-mass
energies from 3.77 to 4.60 GeV using 9 fb-1 of data collected with the BESIII detector …

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 …

The Born cross sections of the process e+ e-→ D* 0 D*-π+ at center-of-mass energies from
4.189 to 4.951 GeV are measured for the first time. The data samples used correspond to an …
