Abstract

The formalism for a new generation of unquenched quark models for baryons is presented. The effects of quark-antiquark pairs are taken into account in an explicit form via a microscopic, QCD-inspired, quark-antiquark creation mechanism. As an application, the quark-antiquark contribution to the spin of the proton is discussed.

Holographic charm and bottom pentaquarks. I. Mass spectra with spin effects

Yizhuang Liu, Maciej A. Nowak, Ismail Zahed

Summary: In this study, the researchers revisit the three nonstrange pentaquarks predicted using holographic dual description, showing that in the heavy quark limit, the pentaquarks with internal heavy quark spin are all degenerate. The holographic pentaquarks are dual to an instanton bound to heavy mesons in bulk, without the shortcomings related to the nature of the interaction and the choice of the hard core inherent to the molecular constructions. Additionally, the study explicitly derived spin-spin and spin-orbit couplings arising from next to leading order in heavy quark mass to lift the internal spin degeneracy.

Coupled channel effects for the charmed-strange mesons

Wei Hao, Yu Lu, Bing-Song Zou

Summary: The systematic calculation of the spectra and hadronic decays of the D-s system was conducted within a coupled channel framework, with unquenched effects induced by the P-3(0) model. The model showed good agreement with experimental results, suggesting that the coupled channel effect provides a coherent description of D-s mesons. Detailed analysis was also provided for various excited states, including D-s0*(2317) and D-s1(2460).

Understanding the nature of Ω(2012) in a coupled-channel approach

Qi-Fang Lu, Hideko Nagahiro, Atsushi Hosaka

Summary: In this study, we analyze the mass and strong decays of the Omega(2012) resonance using a coupled-channel approach. We find a pole at a mass of 2008 MeV and calculate the decay widths and branching fractions, which agree well with experimental measurements. Our results suggest the importance of both the three-quark core and Xi*K over bar channel in describing the Omega(2012) resonance.

Interpretation of the Ωc → π+ Ω(2012) → π+ ((K)over-barΞ) relative to Ωc → π+ (K)over-barΞ from the Ω (2012) molecular perspective

Natsumi Ikeno, Wei-Hong Liang, Genaro Toledo, Eulogio Oset

Summary: We present a mechanism for Omega(c) -> pi(+)Omega (2012) production through an external emission Cabibbo favored weak decay mode, where the Omega(2012) is dynamically generated from the interaction of (K) over bar Xi(*) (1530) and eta Omega. The results show that Omega(2012) decays to (K) over bar Xi and are consistent with Belle data. Furthermore, the direct decays Omega(0)(c) -> pi K-+(-)Xi(0) and Omega(0)(c) -> pi(+)(K) over bar Xi* pi(+)eta Omega, account for about (12-20)% of the total Omega(c) -> pi K-+(-)Xi(0) decay rate.

Strong decay widths and mass spectra of charmed baryons

H. Garcia-Tecocoatzi, A. Giachino, J. Li, A. Ramirez-Morales, E. Santopinto

Summary: The total decay widths of the charmed baryons are calculated using the 3P0 model. Both the charmed baryon-(vector/pseudoscalar) meson pairs and the (octet/decuplet) baryon-(pseudoscalar/vector) charmed meson pairs are considered, within a constituent quark model. The masses of the charmed baryon ground states and their excitations up to the D-wave are also calculated using a Hamiltonian model, with parameters fitted to experimental data.

Summary: In this study, the spin and parity of Xi(c)(2970)(+) were determined using data collected by the Belle detector at the KEKB collider. The analysis of decay angle distributions favored a spin of 1/2 for this charmed-strange baryon. The measured ratio of decay branching fractions supported a spin-parity of 1/2(+) with a light-quark spin of 0, marking the first determination of these properties for a charmed-strange baryon.

Summary: We present a new measurement of the beam-spin asymmetry, Sigma, for the (gamma) over right arrown -> K+Sigma(-) reaction using quasi-free neutrons in a liquid-deuterium target. The dataset includes previously unmeasured photon energy and angular ranges, providing new constraints for partial wave analyses. The experimental data were obtained using the CLAS detector at JLab, and predictions from an isobar model confirm the sensitivity to specific resonances. The inclusion of this data in partial-wave analyses leads to significant changes in gamma-n couplings of resonances with small branching ratios to the pi N channel.

Semileptonic weak decays of antitriplet charmed baryons in the light-front formalism

C. Q. Geng, Chia-Wei Liu, Tien-Hsueh Tsai

Summary: The semileptonic decays of B-c -> B(n)l(+)nu(l) were systematically studied using the light-front constituent quark model, determining the spin-flavor structures of the constituents in baryons and calculating decay branching ratios and asymmetry parameters. Results are in agreement with experimental data, with predictions for specific decays consistent with literature and verifiable through experiments. Some results for Xi(+(0))(c) semileptonic channels can be tested at various experimental facilities.

Hadronic structure on the light front. I. Instanton effects and quark-antiquark effective potentials

Edward Shuryak, Ismail Zahed

Summary: This paper is the first in a series of papers that investigates the nonperturbative origin of central and spin-dependent forces between quarks. The focus is on meson spectroscopy in the center-of-mass frame. A new dense instanton ensemble model for the QCD vacuum is proposed to explain the interquark forces in mesons, ranging from quarkonia to heavy-light and light-light ones. The subsequent papers will demonstrate how to extend these interactions to the light front and derive the corresponding Hamiltonians, mesonic, and baryonic light front wave functions. The ultimate goal of this series is to bridge the gap between hadronic spectroscopy and partonic observables.

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.

Heavy Hadronic Molecules Coupled with Multiquark States

Yasuhiro Yamaguchi, Hugo Garcia-Tecocoatzi, Alessandro Giachino, Atsushi Hosaka, Elena Santopinto, Sachiko Takeuchi, Makoto Takizawa

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.

Shedding light on nuclear aspects of neutrinoless double beta decay by heavy-ion double charge exchange reactions

F. Cappuzzello, H. Lenske, M. Cavallaro, C. Agodi, N. Auerbach, J. I. Bellone, R. Bijker, S. Burrello, S. Calabrese, D. Carbone, M. Colonna, G. De Gregorio, J. L. Ferreira, D. Gambacurta, H. Garcia-Tecocoatzi, A. Gargano, J. A. Lay, R. Linares, J. Lubian, E. Santopinto, O. Sgouros, V. Soukeras, A. Spatafora

Summary: This article reviews the status and prospects of heavy-ion double charge exchange (HI-DCE) reactions, highlighting their important role in nuclear reaction, nuclear structure, and double beta-decay investigations. The main challenges lie in the tiny cross sections of these processes and the high background generated by competing reactions. However, recent advancements in magnetic spectrometers have aided the development of HI-DCE spectroscopy. Theoretical descriptions of HI-DCE cross sections are also complex due to the involvement of composite nuclei and multiple reaction mechanisms.

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.
