“…Some new techniques were developed to study the fully-heavy tetraquark states in the past years, and we refer interested readers to Refs. [587,588,589,590,591,592,593,594,595,596] for detailed discussions.…”

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 review of the recent experimental and theoretical progresses in this active field. Besides the conventional heavy hadrons, we shall also review the recently observed open heavy flavor tetraquark states X(2900) and T + cc (3875) as well as the hidden heavy flavor multiquark states X(6900), P cs (4459) 0 , Z cs (3985) − , Z cs (4000) + , and Z cs (4220) + . We will also cover the recent progresses on the glueballs and light hybrid mesons, which are the direct manifestations of the non-Abelian SU (3) gauge interaction of the Quantum Chromodynamics in the low-energy region.

“…This structure is expected to be a cccc configuration. The relevant properties of the fully heavy tetraquark state have been studied, such as the decay behavior [21], inner configuration [22][23][24], mass spectra [25][26][27][28][29][30][31][32][33][34][35], and the production mechanism [36][37][38][39][40][41][42][43][44]. The discovery of fully heavy tetraquark state naturally make us speculate that the fully heavy pentaquark state may also exist.…”

“…Within this window, the physical quantity, that is the mass of the light tetraquark state, should be independent of the Borel parameter M 2 B as much as possible. In practice, we will vary √ s 0 by 0.1 GeV to obtain the lower and upper bounds, and hence the uncertainties of √ s 0 [37][38][39][40].…”

Recently, a hadronic state, named η 1 (1855), about 1.86 GeV was observed in BESIII experiment. This finding has a peculiar interest due to its exotic quantum number J P C = 1 −+ . In this paper, we examine the tetraquark interpretation for the structure of η 1 (1855) in the configurations of [1 c ] ss ⊗[1 c ] qq and [1 c ] sq ⊗ [1 c ] sq , and perform a mass spectrum calculation in the framework of QCD sum rules. The results show that the observed η 1 (1855) could be embedded into the [1 c ] ss ⊗ [1 c ] qq configuration.The possible tetraquark and hybrid decay modes are analyzed, which are critical in decoding its inner structure. By the same way, we evaluate as well the ssss molecular state with 1 −+ quantum number and find that there might exist two such ground states.
