Spectrum of cc(b)over-bar(b)over-bar, bc(c)over-bar(c)over-bar, and bc(b)over-bar(b)over-bar tetraquark states in the dynamical diquark model

Halil Mutuk

Summary: This article introduces the dynamical diquark model, which proposes that exotic hadrons can be formed from colored diquarks. Using numerical calculations and approximation methods, the mass spectra of S-wave cc (b) over bar(b) over bar, bc (c) over bar(c) over bar, and bc (b) over bar(b) over bar tetraquark systems are studied, with one of the systems identified as a candidate for a bound state.

Chang Gong et al.

The experimental study of the di-eta(c) channel is useful for understanding the nature of fully heavy tetraquark systems.

The low-lying hidden- and double-charm tetraquark states in a constituent quark model with instanton-induced interaction

Jin-Bao Wang et al.

Summary: In this study, the spectrum of low-lying hidden- and double-charm tetraquark states is investigated using a nonrelativistic quark potential model. The instanton-induced interaction is considered as the residual spin-dependent hyperfine interaction between quarks. The numerical results show that the masses of several tetraquark states studied are close to those of experimentally observed candidates of exotic meson, suggesting the presence of corresponding compact tetraquark components in those observed states.

All-charm tetraquark in front form dynamics

Zhongkui Kuang et al.

Summary: This study examines all-charm tetraquarks using basis light-front quantization in Hamiltonian dynamics, focusing on mass calculations and meson-meson breakup threshold estimates. Results indicate that the lowest two-charm-two-anticharm state is not a tightly bound tetraquark.

Lineshape of the compact fully heavy tetraquark

Zejian Zhuang et al.

Summary: Observing hadrons and their distributions directly in experiments sheds light on the nonperturbative mystery of quantum chromodynamics, with new hadrons challenging current knowledge and providing additional inputs; the observation of fully heavy cc over bar(c) over bar system by LHCb opens a new era for hadron physics, where internal structure is extracted from experimental data.

Masses of fully heavy tetraquark states from a four-quark static potential model

Z. Asadi et al.

Summary: In this article, we studied the ground-state mass of full-heavy tetraquarks cc (c) over bar(c) over bar and bb (b) over bar(b) over bar by solving the nonrelativistic four-body systems. We applied the flux-tube configurations, the tetraquark four-body potential butterfly, and the dimeson potential flip-flop of SU(3) lattice quantum chromodynamics to describe the tetraquark interaction. Our numerical analysis showed that the disconnected and connected static potentials can predict the mass of tetraquarks very close to experimental data.

Fully-heavy tetraquark spectra and production at hadron colliders

Ruilin Zhu

Summary: The study focused on exotic structures observed around 6900 MeV in J/psi-pair mass spectrum, investigating the spectra of fully-heavy tetraquarks and predicting new structures at different energy levels. The production of fully-heavy S-wave tetraquarks at hadron colliders was also explored, obtaining their cross sections.

Higher mass spectra of the fully-charmed and fully-bottom tetraquarks

Feng-Xiao Liu et al.

Summary: In this study, the higher mass spectra for fully-charmed and fully-bottom tetraquark states in 2S and 1D waves were calculated using a nonrelativistic potential quark model. The calculation predicts mass ranges for these states and potential causes for observed structures in experimental data, contributing to the understanding of their properties in strong and magnetic interactions. The potential quark model calculations show more states than observed in experiments, suggesting further research is needed for a comprehensive understanding.

Exotic fully heavy QQQQ over bar tetraquark states in 8[QQ] ⊕ 8[QQ] color configuration

Qi-Nan Wang et al.

Summary: The mass spectra of fully charm and fully bottom tetraquark states were calculated in the 8[QQ overbar] (R) 8[QQ overbar] color configuration, suggesting potential components in LHCb's structures. Masses for fully charm tetraquarks were predicted around 6.3-7.2 GeV, while for fully bottom tetraquarks were calculated around 18.2-18.8 GeV, below two-meson decay thresholds.

Hunting for tetraquarks in ultraperipheral heavy ion collisions

Angelo Esposito et al.

Summary: Ultraperipheral heavy ion collisions are ideal for searching for exotic hadrons, focusing on compact tetraquark model states. The X(6900) is a promising candidate, with estimated production cross sections depending on its quantum numbers. The completion of a flavor-spin multiplet would strongly support the compact tetraquark model.

Mass spectra and wave functions of TQQ(Q)over-bar(Q)over-bar tetraquarks

Qiang Li et al.

Summary: This study investigates compact tetraquark states with fully heavy quark contents, deriving mass spectra and wave functions numerically. The results show the ground state mass ranges for cc (c) over bar(c) over bar and bb (b) over bar(b) over bar tetraquarks. The relativistic wave functions obtained can be used for precise calculations of tetraquark decays, suggesting that the observed X(6900) by LHCb may not be the ground state but possibly an excited state. Additionally, a widely used propagatorlike form factor is also explored and discussed.

Investigation of the stability for fully-heavy bc(h)over-bar(e)over-bar tetraquark states

Zi-Yan Yang et al.

Summary: This study investigates the existence of fully-heavy hidden-flavor bc(b) over bar(c) over bar tetraquark states with various J(PC) values, and shows that these states may be stable under certain conditions. The analysis suggests that both S-wave positive parity and P-wave negative parity tetraquark states exhibit specific mass ranges and potential decay channels.

Systematics of fully heavy tetraquarks

Xin-Zhen Weng et al.

Summary: The study indicates that the energy level of the fully heavy tetraquark is mainly determined by color interaction favoring the color-sextet configuration. The chromomagnetic interaction mixes the color configurations and gives small splitting. Most states may be wide with at least one S-wave decay channel, while one possible narrow state is forbidden due to conservation laws.
