摘要

We show the results of a coupled-channel quark model calculation of the bottomonium spectrum with self-energy corrections due to the coupling to the meson-meson continuum. We also provide results for the open-bottom strong decay amplitudes of higher bottomonia in a P-3(0) model.

Properties of bottomonia in a relativistic quark model

Vipin N. S. Naik, Antony Prakash Monteiro, Praveen P. Dsouza, K. B. Vijaya Kumar

Summary: The mass spectrum of bb states has been obtained using the phenomenological relativistic quark model (RQM), and a study on the M1 and E1 radiative decays of b(b) over bar states has been conducted. The experimental results are in overall agreement with the model calculations, and the possibility of some states being exotic states is explored.

Exclusive photoproduction of B± c and bottomonia pairs

Sebastian Andrade, Marat Siddikov, Ivan Schmidt

Summary: In this paper, the authors analyze the photoproduction of heavy quarkonia pairs including b-quarks and compare the production mechanisms to those of charmonia pairs, finding that the channels involving b-quarks provide a better theoretical understanding. They use the Color Glass Condensate approach to estimate the production cross-sections for electron-hadron colliders and LHC, and identify the production of J/psi eta(c) and B+ (c) B- (c) meson pairs as promising channels for studying quarkonia pair production.

Fireball tomography from bottomonia elliptic flow in relativistic heavy-ion collisions

Partha Pratim Bhaduri, Mubarak Alqahtani, Nicolas Borghini, Amaresh Jaiswal, Michael Strickland

Summary: The study calculates the elliptic flow of bottomonia produced in heavy ion collisions and uses the momentum dependence to gain information about the evolution of the QGP fireball. By employing simulation results from a 3 + 1 D quasiparticle anisotropic hydrodynamic model, the transverse momentum dependence of bottomonia elliptic flow was found to be in reasonable agreement with experimental results from the ALICE and CMS collaborations.

Novel way to the metric of higher dimensional rotating black holes

Amin Aghababaie Dastgerdi, Behrouz Mirza, Naresh Dadhich

Summary: This paper proposes a generalized method for obtaining the Kerr metric and Myers-Perry black hole metric. The method starts with a flat spacetime metric and introduces arbitrary functions in oblate spheroidal coordinates appropriate for rotation to incorporate the gravitational potential due to mass. These functions are determined based on the force experienced by particles.

HyperSCP: Combining Isotopic and Isobaric Labeling for Higher Throughput Single-Cell Proteomics

Yiran Liang, Thy Truong, Aubrianna J. Saxton, Hannah Boekweg, Samuel H. Payne, Pam M. Van Ry, Ryan T. Kelly

Summary: Recent advances in mass spectrometry-based single-cell proteomics have improved sensitivity, but measurement throughput is still limited. To increase throughput, we combined isobaric and isotopic labeling methods for multiplexing. By using SILAC and TMT labeling, we were able to analyze up to 28 single cells in a single LC-MS analysis. With a customized nanowell chip, sample losses were minimized. The measurement throughput could be further increased with a high-duty-cycle multicolumn LC system.

Physics implication from higher weak isospin decomposition

Phung Van Dong, Duong Van Loi

Summary: The SU(3)L circle times U(1)X symmetry is directly broken to the electroweak symmetry SU(2)L circle times U(1)Y by a Higgs triplet, leading to new physics at TeV scale. In contrast, this study proposes that the higher weak isospin SU(3)L can be broken at a much higher energy scale by a Higgs octet, forming an intermediate symmetry SU(2)L circle times U(1)T8 at TeV, before being recombined with U(1)X to define U(1)Y by a Higgs singlet. The remaining nondecoupled physics presents a novel family-nonuniversal abelian model, U(1)T8 circle times U(1)X, which significantly modifies the standard model and provides consistent results for various phenomena.

Higher-dimensional black holes with multiple equal rotations

Eliska Polaskova, Pavel Krtous

Summary: We study the limit of Kerr-(A)dS spacetime where an arbitrary number of rotational parameters is set equal. The resulting metric splits into two parts, one similar to the entire spacetime metric and the other interpretable as Kahler metrics. However, the separation is not integrable, leading to non-independent manifolds. We also reconstruct the original symmetries associated with Killing vectors and Killing tensors. The resulting spacetime represents a special subcase of the generalized Kerr-NUT-(A)dS metric, retaining the full Killing tower of symmetries.

Production of bottomonia states in proton plus proton and heavy-ion collisions

Vineet Kumar, Prashant Shukla, Abhijit Bhattacharyya

Summary: In this work, we review the experimental and theoretical developments of bottomonia production in proton+proton and heavy-ion collisions. The bottomonia production process is proving to be one of the most robust processes to investigate the fundamental aspects of Quantum Chromodynamics at both low and high temperatures. We discuss the measurements in different collision systems, such as proton+proton, proton+Pb, and Pb+Pb, and compare them with various theoretical models to understand the medium effects.

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.
