Exploring fully heavy scalar tetraquarks Q Q Q Q

S. S. Agaev et al.

Summary: This article calculates the masses, couplings, and widths of the fully heavy scalar tetraquarks X4Q = QQQQ, Q = c, b by modeling them as four-quark systems composed of axial-vector diquark and antidiquark. The masses m(') and couplings f(') are computed using the QCD sum rule method and taking into account a nonperturbative term. The possible decay modes and partial widths of the tetraquarks are also evaluated. Comparisons are made with other theoretical predictions and experimental observations.

The S- and P-wave fully charmed tetraquark states and their radial excitations

Guo-Liang Yu et al.

Summary: Inspired by recent progresses in observations of the fully charmed tetraquark states by LHCb, CMS, and ATLAS collaborations, a systematic study is performed on the ground states and first radial excitations of the S- and P-wave cc (c) over bar(c) over bar system. The results from calculations using the relativized quark model show that there are no stable bound states for the fully charmed tetraquark states and their sizes are smaller than 1 fm. The X(6600) structure is suggested to be one of the 0(++)(1S) and 2(++)(1S) states or their mixtures, while X(6900) and X(7200) are proposed to be the corresponding states with different quantum numbers.

Study of X(6900) with unitarized coupled channel scattering amplitudes

Shi-Qing Kuang et al.

Summary: In this paper, the resonant state X(6900) is studied and the scattering amplitudes of coupled channels are calculated using effective Lagrangians. The amplitudes are fitted to experimental data and high-quality solutions are obtained. The extracted pole parameters suggest that X(6900) is a compact tetra-quark.

Going in quest of potential tetraquark interpretations for the newly observed Tψψ states in light of the diquark-antidiquark scenarios

Wen -Chao Dong et al.

Summary: Stimulated by recent experimental progress on T(psi psi) states, the fully charmed tetraquark spectroscopy was investigated using different models. Theoretical results suggest that the T-psi psi(6200), T-psi psi(6600), T-psi psi(6900), and T-psi psi(7300) structures can be interpreted as candidates for fully charmed tetraquark states of different waves. However, due to a lack of experimental information, such as the parities of the observed T-psi psi states, there are uncertainties in the assignments. Further experimental surveys by collaborations such as LHCb, ATLAS, CMS, and others are needed in the future.

Analysis of the X(6600), X(6900), X(7300) and related tetraquark states with the QCD sum rules

Zhi-Gang Wang

Summary: In this study, we re-investigate the mass spectrum of diquark-antidiquark type fully-charm tetraquark states using the QCD sum rules plus Regge trajectories. By taking into account the experimental data from CMS and ATLAS, we perform a self-consistent analysis and propose possible assignments for X(6600), X(6900), and X(7300) within the picture of tetraquark states with the JPC = 0++ or 1+-.

Fully Heavy Tetraquark Spectroscopy in the Relativistic Quark Model

Rudolf N. N. Faustov et al.

Summary: This study calculates the masses of fully heavy tetraquarks' ground and excited states (namely 1P, 2S, 1D, 2P, 3S) comprising charm and bottom quarks and antiquarks. The calculations are based on the diquark-antidiquark picture within the relativistic quark model and employ the quasipotential approach and quantum chromodynamics. The findings demonstrate that most investigated states of tetraquarks exist as broad resonances above the decay thresholds.

Hunting for states in the recent LHCb di-J/ψ invariant mass spectrum

Ze-Rui Liang et al.

Summary: Partial wave analysis was conducted using effective potentials to scrutinize recent LHCb data on the di-J/psi invariant mass spectrum. Coupled-channel effects were taken into account in the production amplitude via final state interactions. A dynamically generated pole structure identified as the X(6900) state was found, along with hints of three other possible states. More experimental data, such as J/psi psi(2S), J/psi psi(3770), and di-psi(2S), are needed for further determination of these states.
