“…Glueballs, composed of the valence gluons, are important for the understanding of non-perturbative QCD [85][86][87], which is asymptotically free [88,89] and at the same time confining [90]. There have been tremendous theoretical studies on them in the past fifty years using various methods and models, such as the MIT bag model [792][793][794][795], fluxtube model [796,797], constituent gluon model [798][799][800][801], AdS/QCD model [802][803][804][805][806][807][808][809][810], lattice QCD [811][812][813][814][815][816][817][818], QCD sum rules [819][820][821][822][823][824][825][826][827], and others [828][829][830].…”

“…Their mass predictions of the low-lying J PC = 0 ±+ /1 ±− /2 ±± /3 ±− three-gluon glueballs are generally consistent with each other, as already shown in table 13 and figure 62. Besides, the J PC = 0 ±− three-gluon glueballs have been investigated in [814,815,817,[982][983][984][985][986][987] through lattice QCD and QCD sum rules. These two glueballs are probably not lowlying any more, as depicted in figure 72.…”

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 Tcc(3875) as well as the hidden heavy flavor multiquark states X(6900), Pcs(4459), Zcs(3985), Zcs(4000), and Zcs(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.

“…The different P-parity glueballs are distinguished by the parameter p, and p = 1 for even and p = −1 for odd. The gauge invariant operators for different J PC glueballs can be obtained from [62][63][64]53]. For the action of the tensor glueballs, the spin-2 field h MN satisfies the following conditions…”

In this paper we present a short overview on the dynamical holographic QCD method for hadron physics and QCD matter. The 5-dimensional dynamical holographic QCD model is constructed in the graviton-dilaton-scalar framework with the dilaton background field $\Phi$ and the scalar field $X$ dual to the gluon condensate and the chiral condensate operator thus can represent the gluodynamics (linear confinement) and chiral dynamics (chiral symmetry breaking), respectively. The dilaton background field and the scalar field are a function of the 5th dimension, which plays the role of the energy scale, in this way, the DhQCD model can resemble the renormalization group from ultraviolet (UV) to infrared (IR). By solving the Einstein equation, the metric structure at IR is automatically deformed by the nonperturbative gluon condensation and chiral condensation in the vacuum. We review the results on the hadron spectra including the glueball spectra, the light/heavy meson spectra, as well as on QCD phase transitions, and thermodynamical as well as transport properties in the framework of the dynamical holographic QCD model.
