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 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 doubly charmed tetraquark T cc+ recently discovered by the LHCb Collaboration is
studied on the basis of (2+ 1)-flavor lattice QCD simulations of the D* D system with nearly …

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 …

We use the leading-order contact interactions and one-pion-exchange potentials to
investigate the newly observed double-charm state T cc+. We employ the complex scaling …

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 …
