摘要

We perform a quantitative analysis of the decays of cc (c) over bar(c) over bar tetraquarks with J(PC) = 0(++), 2(++) into 4 muons and into hidden- and open-charm mesons and estimate, for the first time, the fully charmed tetraquark decay width. The calculated cross section upper limit is similar to 39(780) fb for the 4 muons channel, and similar to 42(616) pb for the D(*) (D) over bar(*) -> e mu channel, in the 0(++)(2(++)) case. Decay widths depend upon the additional parameter xi = vertical bar Psi(T)(0)vertical bar(2)/Psi(J/psi)(0)vertical bar(2), which can be computed with a considerable error. We find Gamma(0(++)) similar to Gamma(2(++)) = 97 +/- 30. On the basis of our results and with the present sensitivity, LHCb should detect both 0(++) and 2(++) fully-charmed tetraquarks.

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.

Mass spectra for the cc(b)over-bar(b)over-bar and bb(c)over-bar(c)over-bar tetraquark states

Qi-Nan Wang, Zi-Yan Yang, Wei Chen, Hua-Xing Chen

Summary: The mass spectra of tetraquark states with different spin-parity quantum numbers were studied, showing that positive parity ground states have lower masses than negative parity channels. Positive parity tetraquarks are predicted to be stable and narrow due to decaying only via weak interaction below the BcBc threshold.

Semileptonic and nonleptonic decays of the axial-vector tetraquark Tbb;(u)over-bar(d)over-bar-

S. S. Agaev, K. Azizi, B. Barsbay, H. Sundu

Summary: In this study, the semileptonic and nonleptonic decays of the double-beauty axial-vector tetraquark T-bb are investigated using the QCD sum rule method. The spectroscopic parameters of the final-state tetraquark are calculated, and the partial widths of the dominant decays are computed in terms of weak form factors. The predictions obtained for the partial widths of the decays are used to improve the theoretical accuracy of the full width and lifetime of the tetraquark T-bb, which are crucial for experimental exploration.

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

Qi-Nan Wang, Zi-Yan Yang, Wei Chen

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.

Searching for doubly charmed tetraquark candidates Tcc and Tcc(s)over-bar in Bc decays

Yuan Li, Ying-Bo He, Xiao-Hai Liu, Baoyi Chen, Hong-Wei Ke

Summary: In this study, we propose to search for the exotic doubly charmed meson T-cc(+) and its analog T-cc (s) over bar(+) in B-c(+) decays, which provide a favorable environment for the formation of the exotic state containing double charm quarks. Through various rescattering processes with different intermediate states, the production of T-cc(+) and T-cc (s) over bar(+) is investigated. The estimated branching ratios of B-c(+) decaying into T-cc(+) (D) over bar (0), T-cc(+) (D) over bar*(0), T-cc (s) over bar (D) over bar (0), and T-cc (s) over bar (D) over bar*(0) are on the order of 10(-7), 10(-5), 10(-6), and 10(-4), respectively, which can be tested in future experiments.

Summary: The first observations of B-0 -> (D) over bar*(2007)K-0(+)pi(-) and B-s(0) -> (D) over bar*(2007)K-0(-)pi(+) decays are presented. These modes can potentially be used to investigate the spectroscopy of charm and charm-strange resonances and to determine the angle gamma of the Cabibbo-Kobayashi-Maskawa unitarity triangle.

Testing leptoquark/EFT in (B)over-bar → D(*)l(v)over-bar at the LHC

Syuhei Iguro, Michihisa Takeuchi, Ryoutaro Watanabe

Summary: The study investigates LHC constraints on New Physics using leptoquark models and an effective-field-theory Hamiltonian. It shows differences between LQs and EFT in terms of applicable LHC bounds. The EFT description is found to be invalid for searching for LQs with mass less than or equal to 10 TeV at the LHC and may lead to overestimated bounds. Future prospects for high luminosity LHC searches include exploring charge asymmetry in background and signal events.

Study of double-charm and double-strange tetraquark Xccs over bar s over bar

Yuheng Wu, Xin Jin, Runxin Liu, Xinmei Zhu, Hongxia Huang, Jialun Ping

Summary: In this study, we explore the double-charm and double-strange tetraquark states with two structures within the framework of the quark delocalization color screening model. We find two new resonance states by applying a stabilization calculation and coupling all channels, with mass and width around 4250 and 6 MeV, and 4300 and 19 MeV, respectively. These states are more likely to be compact resonance states. Although no significant signals were observed in the present experiment, further testing with a larger amount of data is suggested.

D-wave excited cs(c)over-bar(s)over-bar tetraquark states with JPC=1++ and 1+-

Zi-Yan Yang, Wei Chen

Summary: In this study, we investigate the mass spectra of D-wave excited cs (c) over bar(s) over bar tetraquark states with J(PC) = 1(++) and 1(+-) using the QCD sum rule method. Our results suggest that the recently observed X(4685) resonance can be interpreted as a D-wave cs (c) over bar(s) over bar tetraquark state with J(PC) = 1(++) in the (2,0(0,0}) or (0,2{2,0}) excitation mode. We also provide mass relations for the positive and negative C-parity D-wave cs (c) over bar(s) over bar tetraquarks, which can be useful for searching for these potential tetraquark states in various channels.

Summary: In this study, 36 tetraquark configurations were constructed for the tetraquark ss (s) over bar(s) over bar system, and the mass spectrum was predicted using a nonrelativistic potential quark model without the diquark-antidiquark approximation. The resonances f(0)(2200), f(2)(2340), and the newly observed X(2500) were identified as potential candidates for specific tetraquark states, providing guidance for experimental searches. The study also predicted the mass range for certain T-ss (s) over bar(s) over bar states, indicating the likelihood of observing these states in experiments.

Summary: This study investigates the decay of D(D) pairs in quantum-correlated samples, focusing on the decay of K-π(+) and measuring the asymmetry between CP-odd and CP-even eigenstate decays. Additional tagging modes, including K-L(0) meson decay modes, are utilized to improve the accuracy of the measurements. The research also explores the phase space of three-body decays and provides the most precise measurement of δ(K)(π)(D) in quantum-correlated D(D) decays.

Summary: In the past decade, there has been a significant shift in understanding the internal structure of hadrons, with new theoretical techniques and experimental findings suggesting that soft quark+quark (diquark) correlations play a crucial role in hadron physics. These correlations are believed to be a necessary consequence of dynamical chiral symmetry breaking and may be critical for the formation of exotic tetra- and penta-quark hadrons.

Summary: Positron beams, both polarized and unpolarized, are essential for experimental programs at the next generation of lepton accelerators, such as JLab's hadronic physics program. They provide precise understanding of electromagnetic structure of nucleons and nuclei, allow for model-independent determination of electromagnetic form factors, and enable accurate separation of contributions to lepto-production cross sections. Additionally, positron beams offer alternative tests of the Standard Model of particle physics.

Summary: We investigated the coupling between the hidden-charm pentaquarks as a Lambda(c)(D)-Sigma c(D) over bar hadronic molecule and a compact five-quark state. The short-range interaction generated by the coupling to the compact state plays a dominant role in determining the energy-level structures, while the long-range one pion exchange potential (OPEP) affects the decay width.

Summary: The NUMEN project proposes an innovative technique to access nuclear matrix elements through heavy-ion induced Double Charge Exchange reactions, aiming to study the lifetime of double beta decay. Despite being triggered by different types of interactions, similarities in many-body wave functions and transition operators exist between neutrinoless double beta decay and DCE reactions. The upgrade of INFN-LNS facilities, connected to the POTLNSa project, is essential for enabling measurements of DCE cross-section under extremely high beam intensities as required by the NUMEN project.

Summary: This report describes the physics case, detector requirements, and evolving detector concepts for the Electron-Ion Collider (EIC) experimental program. The EIC will be a new facility in the United States with the capability to collide high-energy electron beams with high-energy proton and ion beams, providing access to regions dominated by gluons. The use of polarized beams in the EIC will allow for unprecedented access to the spatial and spin structure of particles. The report aims to advance the physics program and develop detector concepts that meet the requirements for the EIC.

Masses and decay widths of Ξc/b and Ξ′c/b baryons

R. Bijker, H. Garcia-Tecocoatzi, A. Giachino, E. Ortiz-Pacheco, E. Santopinto

Summary: This article presents a complete classification of the negative parity Xi'(c/b) and Xi(c/b) P-wave states and calculates their strong partial decay widths and electromagnetic decay widths. Possible assignments for new and previously reported Xi(c) states are suggested based on the equal-spacing mass rule and the analysis of strong partial decay widths. Recently, the LHCb Collaboration observed two new Xi(b) states that are consistent with the predictions made in this study.

Triply-heavy tetraquarks in an extended relativized quark model

Qi-Fang Lu, Dian-Yong Chen, Yu-Bing Dong, Elena Santopinto

Summary: In this study, an extended relativized quark model was used to investigate triply-heavy tetraquarks, which were found to be unstable and easily decay into heavy quarkonium plus heavy-light mesons. The mass spectra showed similar patterns, maintaining light flavor SU(3) symmetry and heavy quark symmetry well. These findings suggest that triply-heavy tetraquarks are potential candidates for future experimental investigations.

Inhomogeneity of a rotating quark-gluon plasma from holography

Nelson R. F. Braga, Octavio C. Junqueira

Summary: This study investigates the influence of rotation on the transition temperature of strongly interacting matter produced in non-central heavy ion collisions. By using a holographic description of an AdS black hole, the authors extend the analysis to the more realistic case where the matter spreads over a region around the rotational axis. The results show the coexistence of confined and deconfined phases and are consistent with the concept of local temperature in rotating frames developed by Tolman and Ehrenfest.

Constrain the time variation of the gravitational constant via the propagation of gravitational waves

Bing Sun, Jiachen An, Zhoujian Cao

Summary: This paper investigates the effect of gravitational constant variation on the propagation of gravitational waves. By employing two analytical methods, the study finds that variations in the gravitational constant result in amplitude and phase corrections for gravitational waves, and the time variation of the gravitational constant can be constrained through the propagation of gravitational waves.

Quantum tunneling from Schwarzschild black hole in non-commutative gauge theory of gravity

Abdellah Touati, Zaim Slimane

Summary: This letter presents the first study of Hawking radiation as a tunneling process within the framework of non-commutative gauge theory of gravity. The non-commutative Schwarzschild black hole is reconstructed using the Seiberg-Witten map and the star product. The emission spectrum of outgoing massless particles is computed using the quantum tunneling mechanism. The results reveal pure thermal radiation in the low-frequency scenario, but a deviation from pure thermal radiation in the high-frequency scenario due to energy conservation. It is also found that noncommutativity enhances the correlations between successively emitted particles.

Compact stars: To cross or go around? That is the question

Shahar Hod

Summary: The travel times of light signals between two antipodal points on a compact star's surface are calculated for two different trajectories. It is shown that, for highly dense stars, the longer trajectory along the surface may have a shorter travel time as measured by asymptotic observers. A critical value of the dimensionless density-area parameter is determined for constant density stars to distinguish cases where crossing through the star's center or following a semi-circular trajectory on the surface has a shorter travel time as measured by asymptotic observers.
