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 …

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 …

We perform a unitary coupled channel study of the interaction of the D*+ D 0, D* 0 D+
channels and find a state barely bound, very close to isospin I= 0. We take the experimental …

Inspired by the T cc+ signal discovered by the LHCb Collaboration, we systematically
investigate the doubly heavy tetraquark states with the molecule configuration [Q 1 q¯ 2] 1 c …

Very recently, the LHCb Collaboration reported the doubly charmed tetraquark state T cc+
below the D*+ D 0 threshold about 273 keV. As a very near-threshold state, its long-distance …

Recently, the LHCb Collaboration discovered the first doubly charmed baryon Ξ cc++= ccu
at 3621.40±0.78 MeV, very close to our theoretical prediction. We use the same methods to …

In the present work, we investigate the scalar, axialvector and tensor doubly-charmed
tetraquark molecular states without strange, with strange and with doubly-strange via the …

With a quark level interaction, we give a unified description of the loosely bound molecular
systems composed of the heavy flavor hadrons (D¯, D¯∗),(Λ c, Σ c, Σ c∗), and (Ξ c, Ξ c′, Ξ …

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 …
