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

Since the discovery of the first charmed meson in 1976, many open-charm and open-bottom
hadrons were observed. In 2003 two narrow charm-strange states $ D_ {s0}^{\ast}(2317) …

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 …

Motivated by the success of the flavour physics programme carried out over the last decade
at the Large Hadron Collider (LHC), we characterize in detail the physics potential of its High …

Glueballs, hybrids and multiquark states are predicted as bound states in models guided by
quantum chromo dynamics (QCD), by QCD sum rules or QCD on a lattice. Estimates for the …

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 …

In the framework of the chiral quark model along with complex scaling range, we perform a
dynamical study on the low-lying S-wave double-heavy tetraquark states (QQ q¯ q¯, Q= c, b …

According to the classification of the quark model, the hadrons going beyond three-quark
baryon and quark-antiquark meson pictures are called exotic hadrons. Many new hadrons …

The recently discovered T c c+ is evaluated as a DD⁎ molecular structure in the JP= 1+
sector. A coupled-channels calculation in charged basis, considering the D 0 D⁎+, D+ D⁎ 0 …

We investigate the tetraquark bound states that are manifestly exotic using three distinct few-
body methods; Gaussian expansion method (GEM), resonating group method (RGM), and …
