摘要

The diquark-diquark-antiquark model describes pentaquark states both in terms of quarks and hadrons. The latest LHCb data for pentaquarks with open charm emphasize the importance of hadron components in the structure of pentaquarks. We discuss pentaquark states with hidden charm ((c) over bar cuud) and those with open charm P((u) over bar ussc) which were discovered recently in LHCb data (J/Psi p and Xi(+)(c) K- spectra correspondingly). Considering the observed states as members of the lowest (s-wave) multiplet, we discuss the mass splitting of states and the dumping of their widths.

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

Wen -Chao Dong, Zhi-Gang Wang

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.

New reaction approach to reflect exotic structure of hadronic molecular state

Zuo-Ming Ding, Jun He, Xiang Liu

Summary: With the increase in experimental data, the presence of more exotic hadrons has been observed. Two popular interpretations of these exotic hadrons are the molecular state and compact multiquark. Determining the structure of an exotic hadron is still challenging. This study proposes a method to detect the internal structure of an exotic state by analyzing the reaction of a molecular state attacked by another particle, which results in one constituent being kicked out while another remains unaffected. The internal structure of the X(3872) is examined as an example, showing different effects based on the assumed molecular state or compact tetraquark state.

Asymptotic mass limit of large fully heavy compact multiquarks

M. C. Gordillo, J. M. Alcaraz-Pelegrina

Summary: Using a diffusion Monte Carlo technique, this study calculated the properties of fully heavy arrangements, including a range of 5 to 12 quarks. The analysis found that the mass per particle levels off for arrangements with the number of quarks larger than or equal to six, implying that fully heavy multiquarks are compact structures.

Exotic hadrons from scattering in the diabatic dynamical diquark model

Richard F. Lebed, Steven R. Martinez

Summary: The diabatic framework extends the adiabatic approximation of the Born-Oppenheimer formalism, incorporating mixing of BO-approximation eigenstates with two-particle thresholds. By applying this framework to the study of hidden-charm dynamical diquark tetraquark states with open-charm dimeson thresholds, the development of resonances and threshold cusp effects can be observed. The example of & chi;c1(3872) illustrates the origin of diquark-antidiquark states enhanced by the D0 over bar D*0 threshold in the 1++ channel.

Quark-diquark potential and diquark mass from lattice QCD

Kai Watanabe

Summary: This study proposes a new application of lattice QCD to calculate the quark-diquark potential, diquark mass, and quark mass. The HAL QCD method is used to calculate the charm-diquark potential and suggests that the weakening of the attraction may be attributed to the diquark size effect.

Diabatic representation of exotic hadrons in the dynamical diquark model

Richard F. Lebed, Steven R. Martinez

Summary: In this study, the diabatic formalism is applied to investigate exotic multiquark hadrons, revealing that the X(3872) state contains both D0 over bar D*0 and diquark-antidiquark components, which significantly contribute to its radiative decay widths.

Investigating full-heavy tetraquarks composed of cc(c)over-bar(b)over-bar and bb(b)over-bar(c)over-bar

Jing Hu, Bing-Ran He, Jia-Lun Ping

Summary: The properties of full-heavy tetraquarks cc(c) over bar(b) over bar and bb(b) over bar(c) over bar are systematically investigated in this study, considering the meson-meson structure, diquark-antidiquark structure, and K-structure. No bound state is found for the cc(c) over bar(b) over bar and bb(b) over bar(c) over bar systems in IJ(P)=00(+), 01(+), and 02(+) channels. However, three possible resonance states with energies of 10,079 MeV, 10,081 MeV, and 10,177 MeV are observed in the cc(c) over bar(b) over bar system in IJP=00(+), 01(+), and 02(+) channels, respectively, with decay widths Gamma of 6.7-8.4 MeV, 1.4-7.2 MeV, and 9.1-11.1 MeV. Similarly, the bb(b) over bar(c) over bar system also exhibits three possible resonance states with energies of 16,474 MeV, 16,474 MeV, and 16,541 MeV in IJP=00(+), 01(+), and 02(+) channels, respectively, with decay widths Gamma of 2.2-6.1 MeV, 2.2-6.9 MeV, and 5.3-8.5 MeV. The bc(c) over bar(c) over bar and cb(b) over bar(b) over bar systems yield the same results as the cc(c) over bar(b) over bar and bb(b) over bar(c) over bar systems, respectively. These full-heavy resonance states are worth searching for in future experiments.

Properties of Strange Quark Matter in the Context of Diquark Correlation

Aparajita Bhattacharya, Shukla Pal, Papiya Dhara, Deb Sankar Bhattacharya

Summary: Properties of strange quark matter have been investigated, considering it as diquark matter with quark correlation. It is observed that diquarks exhibit quasiparticle behavior under strong magnetic field. Furthermore, using the composite fermion model, the binding energy of the system is reduced, resulting in a more stable state of strange quark matter.

Doubly heavy tetraquarks in a chiral-diquark picture

Yonghee Kim, Makoto Oka, Kei Suzuki

Summary: The energy spectrum of doubly heavy tetraquarks, TQQ (QQq??q?? with Q = c, b and q = u, d, s), is investigated in the potential chiral-diquark model. The Tbb, Tcc, and Tcb tetraquarks are described as a three-body system composed of two heavy quarks and an antidiquark. Several Tbb bound states are found, and the change of TQQ tetraquark masses under restoration of chiral symmetry is also studied.

Nonrelativistic treatment of fully-heavy tetraquarks as diquark-antidiquark states

Halil Mutuk

Summary: This study aimed to estimate the masses of ground and excited states of fully-heavy tetraquark systems using a nonrelativistic model. The predicted masses of ground states were found to be higher than the decay thresholds, making them difficult to observe experimentally, while the first excited states showed lower masses compared to their respective thresholds, suggesting potential observability in experiments.

Role of Martensite-Austenite Component of Bainitic Structure in Formation of Properties of Pipe Steel. 1. Effect of Parameters of TMT

N. G. Kolbasnikov, S. A. Kuzin, V. S. Teteryatnikov, N. Zhukov, R. R. Adigamov, M. S. Sakharov, M. A. Matveev

Summary: The effect of hot rolling and controlled cooling parameters on the formation of the martensite-austenite component in bainitic and ferritic-bainitic structures of K60 pipe steel was studied. Experimental results showed that the volume fraction of the martensite-austenite component varied from 0.5% to 8% depending on the parameters of the thermomechanical treatment. The accumulated strain was found to play a dominant role in the formation of martensite-austenite particles and the determination of the acicular ferrite fraction.

Role of Martensite-Austenite Component of Bainitic Structure in Formation of Properties of Pipe Steel. 3. Effect of Martensitic Transformation of Austenite in the MA-Component of Bainite on the Ductility of Steel

N. G. Kolbasnikov, A. M. Zaitsev, R. R. Adigamov, M. S. Sakharov, M. A. Matveev

Summary: The behavior of low-carbon pipe steel containing 2 and 6 vol.% martensitic-austenitic component in the structure is studied under step forming, expanding and unbending of the pipe using the method of finite-element simulation. The effect of martensitic transformation in the MA-component on the ductility of the steel after processing and unbending of the pipe depending on the volume fraction of the MA-particles in the structure and on the test conditions (the direction of cutting of the samples and the stresses at the start of martensitic transformation) is studied. It is shown that the presence of untransformed austenite in the MA-component can restore partially the ductility of the steel lost due to the plastic deformation during processing of the pipe.

Summary: This research extends the understanding of the thermal and deformation stability of untransformed austenite in the martensitic-austenitic component of low-carbon steel bainitic structure, through experimental and theoretical studies. The analysis of compressive hydrostatic stresses during dilatation provides the relationships to determine the temperature at which martensitic transformation begins in the MA-component, as well as the level of deformation caused by strain-induced martensitic transformation.
