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 …

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 …

In the past decade, exotic hadrons with charm and bottom flavors have been extensively
studied both in experiments and in theories. In this review, we provide topical discussions by …

High energy heavy ion collisions are excellent ways for producing heavy hadrons and
composite particles, including the light (anti) nuclei. With upgraded detectors at the …

We discuss selected and important features of hadronic molecules as one of several
promising forms of exotic hadrons near thresholds. Using examples of $ D {\bar {D}}^{*} …

We discuss the properties of hadronic systems containing one heavy quark in the heavy
quark limit. The heavy quark symmetry guarantees the mass degeneracy of the states with …

The recently discovered Z c (3900) meson is a flavor-exotic tetraquark whose constituents
consist of a charm quark and antiquark and a light quark and antiquark. We identify such …

The most recent experimental data for all measured production and decay channels of the
bottomoniumlike states Z b (10610) and Z b (10650) are analyzed simultaneously using …

We study heavy hadron spectroscopy near open bottom thresholds. We employ B and B*
mesons as effective degrees of freedom near the thresholds, and consider meson exchange …

The decays of the Z b (10610) and the Z b (10650) to Υ (n S) π, hb (m P) π and χ b J (m P) γ
(n= 1, 2, 3, m= 1, 2 and J= 0, 1, 2) are investigated within a nonrelativistic effective field …
