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

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 …

Using proton-proton collision data at centre-of-mass energies of s= 7, 8 and 13 TeV
recorded by the LHCb experiment at the Large Hadron Collider, corresponding to an …

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 …

There are eighteen possibly existing D (*) D¯(*), D (*) K¯(*), and D (*) D s (*)-hadronic
molecular states. We construct their corresponding interpolating currents and calculate their …

The question of whether there exist bound states of two heavy quarks Q=(c, b) and
antiquarks Q¯=(c¯, b¯), distinct from a pair of quark-antiquark mesons, has been debated for …

Using a relativized diquark model Hamiltonian, we calculate the masses of J^ PC= 0^++ J
PC= 0++ ground-state tetraquarks in the following systems: bs ̄ b ̄ s bsb¯ s¯, bb ̄ n ̄ n …

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

In the framework of the color-magnetic interaction, we systematically investigate the mass
spectrum of the tetraquark states composed of four heavy quarks with the QQQ¯ Q¯ …

It has been 5 years since the data sample from the LHCb detector, the first experiment
optimized for heavy-flavor physics studies at a hadronic collider, was completed. These data …
