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 …

The spectrum of hadronic molecules composed of heavy–antiheavy charmed hadrons has
been obtained in our previous work. The potentials are constants at the leading order, which …

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 …

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 …

A coupled channel analysis of the D⁎+ D 0 and D⁎ 0 D+ system is performed to study the
doubly charmed T c c+ state recently discovered by the LHCb collaboration. We use a …

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 investigate the possibility of qq′ b¯ b¯ tetraquark bound states using nf= 2+ 1 lattice
QCD ensembles with pion masses≃ 164, 299, and 415 MeV. Motivated by observations …

With the development of high energy physics experiments, a large amount of exotic states in
the hadronic sector have been observed. In order to shed some light on the nature of the …

About 120 baryons and baryon resonances are known, from the abundant nucleon with u
and d light-quark constituents up to the Ξ b−=(bsd), which contains one quark of each …
