Using the nonrelativisitc reduction of Coulomb gauge QCD we compute a spectrum of the low mass hybrid mesons containing a heavy quark-antiquark pair. The gluon degrees of freedom are treated in the mean field approximation calibrated to the gluelump spectrum. We discuss the role of the non-Abelian nature of the QCD Coulomb interaction in the ordering of the spin-parity levels.

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: The study discusses two complementary strategies to search for light dark matter using positron beam at Jefferson Laboratory. These strategies, utilizing the high intensity and energy of the CEBAF beam and a novel LDM production mechanism, aim to explore new regions in the LDM parameter space, thoroughly probing the LDM hypothesis and hidden sector scenarios.

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.

Nuclear reactions in artificial traps

Peng Guo, Bingwei Long

Summary: This paper discusses couple-channel two-particle systems bound by a harmonic trap, deriving a formula that relates the energy levels of such trapped systems to phase shifts and inelasticity of coupled-channel reactions. It may lay some groundwork towards extracting scattering amplitudes of inelastic nuclear reactions from ab initio calculations of discrete levels of many-nucleon systems in a harmonic trap.

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.

Anomalous Faraday effect in a PT-symmetric dielectric slab

Vladimir Gasparian, Peng Guo, Esther Jodar

Summary: In this letter, we discuss a phase transition-like anomalous behavior of Faraday rotation angles in a simple parity-time (PT) symmetric model. In the anomalous phase, one of the Faraday rotation angles becomes negative, and both angles exhibit spectral singularities and strong enhancement near the singularities.

Polar magneto-optic Kerr and Faraday effects in finite periodic PT-symmetric systems

Antonio Perez-Garrido, Peng Guo, Vladimir Gasparian, Esther Jodar

Summary: We discuss the anomalous behavior of Faraday and Kerr rotation angles in finite periodic PT-symmetric structures. It is shown that a phase transition-like anomalous behavior can occur, where one of the rotation angles becomes negative and both angles have spectral singularities. We also find a relationship between the real and imaginary parts of the Kerr and Faraday rotation angles.

Tunneling time in PT-symmetric systems

Peng Guo, Vladimir Gasparian, Esther Jodar, Christopher Wisehart

Summary: In this study, we propose a generalized approach to tunneling time in parity and time (PT)-symmetric systems. The properties of tunneling time in PT-symmetric systems are examined using a simple contact interaction periodic finite-size diatomic PT-symmetric model. The physical interpretation of negative tunneling time in PT-symmetric systems and its relationship to spectral singularities are discussed.

Transfer reactions between odd-odd and even-even nuclei by using the interacting boson fermion fermion model and 0νββ decay in closure approximation

Ruslan Idelfonso Magana Vsevolodovna, Elena Santopinto, Roelof Bijker

Summary: This study presents the formulation and operators for computing spectroscopic amplitudes in the IBFFM scheme, and improves the description of odd-odd nuclei using machine learning techniques. This method can be used to calculate cross sections of heavy-ion reactions and extract the contributions of each orbital.

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.
