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 …

In the past two decades, a plethora of hadronic states beyond the conventional quark model
of qq ̄ mesons and qqq baryons have been observed experimentally, which motivated …

The first evidence for X (3872) production in relativistic heavy ion collisions is reported. The
X (3872) production is studied in lead-lead (Pb-Pb) collisions at a center-of-mass energy of s …

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 …

We calculate the masses of the(;) tetraquark states with the aid of heavy diquark-antiquark
symmetry (HDAS) and the chromomagnetic interaction (CMI) model. The masses of the …

The past decade witnessed a remarkable proliferation of exotic charmonium-like
resonances discovered at accelerators. In particular, the recently observed charged states …

The Λ (1405) baryon resonance plays an outstanding role in various aspects in hadron and
nuclear physics. It has been considered that the Λ (1405) resonance is generated by the …

The structure of exotic resonances that do not trivially fit the usual quark model expectations
has been a matter of intense scientific debate during the last two decades. A possible way of …

Loosely-bound objects such as light nuclei are copiously produced in proton-proton and
nuclear collisions at the Large Hadron Collider (LHC), despite the fact that typical energy …
