摘要

Inspired by the recent findings of the two P-c(+) states in the J/psi p mass spectrum at LHCb, we investigate the elastic and inelastic cross sections of the J/psi N, eta N-c, eta N-b and eta N-b channels within the constraints from heavy quark spin and flavor symmetry. The (D) over bar ((*)) Sigma(()(c)*()) (B-(*()) Sigma(()(b)*())) bound states predicted in earlier works should be accessible in elastic and/ or inelastic processes of the J/psi N and/or eta N-c (gamma N and/or eta N-b) interactions.

Semileptonic Bc → ηc, J/ψ transitions

Zhao-Qian Yao, Daniele Binosi, Zhu-Fang Cui, Craig D. Roberts

Summary: Using a systematic, symmetry-preserving continuum approach, parameter-free predictions were made for all semileptonic B-c -> eta(c), J/psi transition form factors. The study confirms a 2 sigma discrepancy between the Standard Model prediction for R-J/psi and the single available experimental result.

Semileptonic decay of Bc to ηc and J/ψ on the light front

Shuo Tang, Shaoyang Jia, Pieter Maris, James P. Vary

Summary: This study investigates the semileptonic decay of B-c(0(-)) to charmonia via the bottom-to-charm-quark electroweak current using basis light-front quantization. Weak transition form factors for decays into eta(c) or J/psi are calculated based on initial and final valence light-front wave functions, leading to differential decay width, branching ratios, and observations of unphysical frame dependence. A preferred set of frames is proposed for calculating these form factors based on analysis of the current component.

Phenomenological studies on neutral B-meson decays into J/Ψ f1 and ηc f1

De-Hua Yao, Xin Liu, Zhi-Tian Zou, Ying Li, Zhen-Jun Xiao

Summary: The B-d,s(0) -> J/psi f(1)(1285, 1420) and B-d,s(0)-> eta(c)f(1)(1285, 1420) decays are studied in the perturbative QCD (PQCD) approach, including vertex corrections, nonfactorizable diagrams, and penguin operators. Branching fractions, direct CP asymmetries, and polarization fractions are calculated. The results show that these decays can be measured in the LHCb and Belle-II experiments, and the B-s(0) -> (J /psi, eta(c))f(1)(1420) decays have larger branching fractions compared to the B-d(0) -> J/psi f(1)(1285) decays.

One-loop corrections to the processes e+e- → γ, Z → J/ψηc and e+e- → Z→ J/ψ J/ψ

A. Berezhnoy, I. N. Belov, S. Poslavsky, A. K. Likhoded

Summary: The production cross sections of J/psi eta(c) and J/psi J/psi in e(+)e(-) annihilation were calculated with a one-loop accuracy near the Z-boson pole and at higher energies. It was found that the next-to-leading contribution at the Z mass increases the production cross sections by a factor of 3.5.

Structure around p(p)over-bar threshold in J/ψ radiative decays

Qin-He Yang, Di Guo, Ling-Yun Dai

Summary: This paper investigates the structure around the p (p) over bar threshold observed in the eta 'pi(+) pi(-), 3(pi(+) pi(-)), and (KSKS0)-K-0 eta invariant mass spectra of relevant J/psi radiative decays. The study includes the N (N) over bar rescattering and applies the distorted-wave Born approximation to calculate the decaying amplitude. The scattering amplitudes of N (N) over bar are obtained through solving the Lippmann-Schwinger equation with potentials from chiral effective field theory.

Understanding J/ψ and ψ' production using a modified version of Non-Relativistic Quantum Chromodynamics

Sudhansu S. Biswal, Sushree S. Mishra, K. Sridhar

Summary: There is a long-standing disagreement between the predictions of NRQCD and J/. polarization data. By accounting for the effect of soft gluons, this study proposes a solution to the polarization problem and successfully fits the experimental data from Tevatron. The non-perturbative parameters obtained can be used to make parameter-free predictions for CMS experiment at the Large Hadron Collider, which are in excellent agreement with the CMS data.

Next-to-leading-order study of J/ψ angular distributions in e+e-→ J/ψ + ηc, χcJ at √s ≈ 10.6 GeV

Zhan Sun

Summary: This paper presents a detailed NLO study of J/psi angular distributions in e(+) e(-) -> J/psi + eta(c), chi(cJ) (J = 0, 1, 2) within NRQCD, deriving numerical expressions for total and differential cross sections. By comparing with experiment, it is found that the predicted result for J/psi + eta(c) is in good agreement with Belle measurement, while the result for J/psi + chi(c0) is totally incompatible with experimental data.

Cross sections and isomer ratios in the Rb(n,γ) and Sr(n,γ) reactions

K. S. Krane

Summary: Neutron radiative capture cross sections were measured for stable isotopes of Rb and Sr using the activation technique, providing values for thermal cross sections, resonance integrals, and isomer ratios. Spectroscopic studies improved values for gamma ray energies emitted in decays of certain isotopes. Additionally, the half-life of Sr-87m was remeasured to resolve conflicting values reported in the literature.

Inclusive production of J/ψ, ψ(2S), and γ states in pNRQCD

Nora Brambilla, Hee Sok Chung, Antonio Vairo, Xiang-Peng Wang

Summary: Under assumptions on energy scales, this study calculates long-distance matrix elements (LDMEs) for J/psi, psi(2S), and gamma states using the potential NRQCD (pNRQCD) effective field theory. Based on the pNRQCD formalism, expressions for LDMEs are obtained in terms of quarkonium wavefunctions and gluonic correlators, reducing nonperturbative unknowns. Improved determinations of LDMEs and phenomenological results for cross sections and polarizations are achieved, agreeing well with LHC measurements.
