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 …

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 …

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

The P_c(4380)^+ and P_c(4450)^+ states recently discovered at LHCb have masses close
to several relevant thresholds, which suggests they can be described in terms of meson …

We have performed a coupled channel calculation of the 1++ cc¯ sector including qq¯ and
DD* molecular configurations. The calculation was done within a constituent quark model …

Inspired by the discovery of two pentaquarks P_ c (4380) P c (4380) and P_ c (4450) P c
(4450) at the LHCb detector, we study possible hidden-charm molecular pentaquarks in the …

We systematically investigate the stability of the doubly heavy tetraquark states Q_1Q_2 ̄ q

Binding energies and widths of three-body K¯ NN, and of four-body K¯ NNN and K¯ K¯ NN
nuclear quasibound states are calculated in the hyperspherical basis, using realistic NN …
