Double-heavy tetraquark states with heavy diquark-antiquark symmetry

Jian-Bo Cheng et al.

Summary: In this study, the masses of QQ (q) over bar(q) over bar tetraquark states are calculated using the HDAS and CMI model. The results indicate that double-charm tetraquarks are unstable, while stable double-bottom tetraquarks have specific mass ranges.

Perfect DD* Molecular Prediction Matching the T cc Observation at LHCb

Ning Li et al.

Summary: In 2012, a study identified a loosely bound molecular state composed of two charmed mesons, which is very close to the D*D threshold with a binding energy of around 0.47 MeV. This prediction was later confirmed by new observations from the LHCb.

On the nature of near-threshold bound and virtual states

Inka Matuschek et al.

Summary: The method of uniquely characterizing physical states by their pole positions and residues is extended to shallow virtual states classification. It is argued that mainly non-molecular or compact states exist as bound states or resonances, but not as virtual states. The limitations of the mentioned classification scheme are also discussed.

Heavy Tetraquarks in the Relativistic Quark Model

Rudolf N. Faustov et al.

Summary: The masses of tetraquarks with two and four heavy quarks were calculated in the relativistic quark model using the quasipotential approach and QCD, based on the diquark-antidiquark picture. A comparison with experimental data revealed numerous candidates for tetraquarks, with the recent structures observed in the di-J/psi mass spectrum potentially corresponding to ccc over bar c over bar tetraquarks.

A survey of heavy-heavy hadronic molecules

Xiang-Kun Dong et al.

Summary: In this study, the spectrum of hadronic molecules composed of heavy-antiheavy charmed hadrons was examined, with experimental candidates such as X(3872) and Y(4260) fitting well. The success in describing heavy-antiheavy hadronic molecules led to predictions for heavy-heavy cases, highlighting the potential existence of DD* and D-(*)Sigma((*))(c) molecules. Recent experimental findings support the existence of heavy-heavy hadronic molecules, providing opportunities for further observation in upcoming LHCb and other experiments.

Summary: In this study, a systematic investigation was conducted on potential hidden and doubly heavy molecular states with open and hidden strangeness using a quasipotential Bethe-Salpeter equation approach. The results suggest that the recently observed Zcs (3985) may be a molecular state, and support the existence of hidden heavy states with different spin parities.

Summary: This study investigates the nature of three narrow hidden-charm pentaquark states, suggesting P-c(4312) as a Sigma(c)D hadronic molecule, P-c(4440) and P-c(4457) as a Sigma(c)D and Sigma(c)D* hadronic molecules respectively, and identifies a new narrow state P-c(4380). The analysis reveals that the data is consistent with the proposed interpretations.

Production of Tcc plus exotic state in the γp → D plus T over line cc- Λc plus reaction

Yin Huang et al.

Summary: This study proposes the production of a new exotic charged structure T+cc using the central diffractive mechanism, with the total cross sections of the corresponding reaction evaluated based on chiral unitary theory. The results suggest that the cross section for the gamma p -> D+ T over bar -ccA+c reaction can be measured in proposed Electron-Ion Collider in China or experiments in the U.S., potentially verifying the nature of T+cc.

Production of doubly charmed exotic hadrons in heavy ion collisions

Yuanyuan Hu et al.

Summary: This paper demonstrates how heavy ion collisions can serve as a powerful platform for studying doubly charmed exotic hadrons, providing valuable insights into the dynamics of hadron structures in a charm-rich environment. The yields of T-cc(+) and its isospin partners in Pb-Pb collisions show significant enhancements compared to proton-proton collisions. The results on rapidity, transverse momentum dependence, and elliptic flow coefficient can be further tested by future experimental measurements.

Summary: Researchers have discovered the tetraquark system T thorn cc, which may have a significant molecular component, and have calculated its decay process and differential spectrum in good agreement with experimental measurements. Furthermore, it is pointed out that the existence of shallow bound states of two pseudoscalar charm mesons can significantly enhance the width of T thorn cc if present.

D0D0 π+ mass distribution in the production of the Tcc exotic state

A. Feijoo et al.

Summary: In this study, a unitary coupled channel analysis was performed on the interaction of the D*D-+(0), D*D-0(+) channels, revealing a state that is barely bound and very close to isospin I = 0. Using experimental data as input, the width of the state and the (DD0π-)-D0+ mass distribution were obtained, showing good agreement with results from other data analyses. When considering experimental resolution, the width of the state was found to be about 43 keV, a significant difference from the initial findings.

Color and baryon number fluctuation of preconfinement system in production process and Tcc structure

Yi Jin et al.

Summary: This study suggests investigating the production mechanism and properties of the recently observed T-cc resonance to probe its structure. The similarity between T-cc and Xi(cc) can be determined by examining their production properties and kinematics spectra. Additionally, measuring the momentum correlation of DD* can help determine if T-cc is produced as a hadron molecule. The current cross-section calculations using a nonrelativistic hadron molecule model are significantly lower than experimental measurements.

Doubly heavy tetraquarks, qq'(QQ)over-bar', in a nonrelativistic quark model with a complete set of harmonic oscillator bases

Sungsik Noh et al.

Summary: The study improves the nonrelativistic quark model by introducing a complete set of three-dimensional harmonic oscillator bases and validates the method by comparing calculated binding energies with exact values for the hydrogen model. The new method is applied to analyze double heavy tetraquark states and calculate ground state masses, with certain states found to be stable against the two lowest threshold meson states. The study also discusses the spatial sizes of the tetraquarks.

Masses of doubly heavy tetraquarks with error bars

Eric Braaten et al.

Summary: In the heavy-quark limit, two heavy quarks in a doubly heavy baryon or tetraquark are bound into a compact diquark by their color-Coulomb potential. The doubly heavy hadrons are related to heavy hadrons obtained by replacing the heavy diquark with a heavy antiquark, based on the heavy-quark-diquark symmetry of QCD. Effective field theories can be used to approximate the masses of singly heavy and doubly heavy hadrons by expanding them in inverse powers of heavy-quark masses. The masses of ground-state doubly heavy tetraquarks, predicted to be stable against strong decays, can be determined based on experimental measurements of heavy mesons and baryons, as well as lattice QCD calculations for doubly heavy baryons.
