Summary: We measured the strange axial coupling constant gsA using atmospheric neutrino data at KamLAND. This constant is a component of the axial form factor of the neutral-current quasielastic (NCQE) interaction. The value of gsA significantly affects the ratio of proton and neutron NCQE cross sections. KamLAND is well-suited for such measurements due to its ability to detect nucleon recoils with low-energy thresholds and measure neutron multiplicity with high efficiency.

Summary: This Letter reports high statistic differential cross sections for neutrino-induced charged-current single pi+ production in the Delta(1232) resonance region. The study observes suppression of the cross section at low Q2 and enhancement of low T pi in both light and heavy nuclear targets. The cross sections per nucleon for iron and lead compared with CH across the kinematic variables probed are also different from current predictions by neutrino interaction generators.

Lepton universality violation from neutral pion decays in RK(*) measurements

Dean J. Robinson

Summary: In this study, the potential sources of lepton flavor universality violation (LFUV) in the neutral pion decay of B->K-(*())pi(0)gamma, with pi(0) -> ee gamma, are investigated. The author presents a conservative estimate and simulation of the B -> K pi(0)gamma LFUV background at LHCb, indicating that this effect could reduce the recovered R-K by several percent.

Ignacio Borsa, Daniel de Florian, Ivan Pedron

Summary: This article calculates the fully differential single-jet production in longitudinally polarized deep inelastic scattering (DIS) at next-to-next-to-leading-order (NNLO) accuracy, including both neutral-current and charged-current processes. The computation is performed using the projection-to-Born method, with the next-to-leading-order dijet calculation and the NNLO DIS structure functions as the main components. The article also analyzes its phenomenological consequences in the kinematics of the future Electron-Ion Collider.

Coherent ground-state transport of neutral atoms

X. X. Li, J. B. You, X. Q. Shao, Weibin Li

Summary: This study combines the Rydberg pumping mechanism and the diagonal form of van der Waals interactions to construct a theoretical model for long-range coherent transport inside the ground-state manifold of neutral atoms systems. The model can simulate various single-body physics phenomena and effectively avoid the influence of atomic spontaneous emission.

Coherent pion production in neutrino (anti-neutrino)-nucleus interaction

Hariom Sogarwal, Prashant Shukla

Summary: In this study, coherent pion production in neutrino-nucleus interactions is investigated using the formalism based on the partially conserved axial current theorem. The cross section for neutrino-nucleus interactions is connected to the pion-nucleus elastic scattering cross section. The pion-nucleus elastic scattering cross section is calculated using the Glauber model, which takes into account nuclear densities, pion-nucleon cross section, and the ratio of real to imaginary part of the pi N forward scattering amplitude. The calculated cross sections for charge and neutral current coherent pion production are compared with measured data and calculations from the Berger-Sehgal model and GENIE package. The Glauber model shows excellent agreement with the measured data, and the present calculations describe the data in all energy ranges. Predictions are made for upcoming experiments in the coherent region of neutrino cross section.

Electric current and heat production by a neutral carrier: an effect of the axion

Iver H. Brevik, Moshe M. Chaichian

Summary: A general axion-electrodynamic formalism is presented for explaining the phenomena of strong magnetic fields and strong electric fields in a dielectric environment. The study estimates and calculates the heat generation in a long material cylinder, showing that heat is produced in the presence of a strong magnetic field but not in the presence of a strong electric field. The study also discusses the application of boundary conditions in a quantum mechanical context.

Triangle singularity in the production of T cc+ (3875) and a soft pion

Eric Braaten, Li-Ping He, Kevin Ingles, Jun Jiang

Summary: The double-charm tetraquark meson T-cc(+)(3875) can be produced in high-energy proton-proton collisions. It can be formed by the creation of charm mesons D*+D0 at short distances followed by their binding, or by the creation of D*+D*+ at short distances followed by their rescattering. A narrow peak is observed in the T-cc(+)pi(+) invariant mass distribution, 6.1 MeV above the threshold, with a width of about 1 MeV, due to a charm-meson triangle singularity. Beyond the peak, the differential cross section decreases with the invariant kinetic energy E of T-cc(+)pi(+) as E-1/2. The fraction of T(cc)(+) events accompanied by pi+ with energy less than the mass of pi is estimated to be roughly 3%. The fraction of T(cc)(+) events with T-cc(+)pi(+) in the narrow peak from the triangle singularity could be comparable.

Analyses of multi-pion Bose-Einstein correlations for granular sources with coherent pion-emission droplets

Ghulam Bary, Wei-Ning Zhang, Peng Ru, Jing Yang

Summary: The study reveals that the intercepts of multi-pion Bose-Einstein correlation functions for granular sources with coherent pion-emission droplets are sensitive to the number of droplets, decreasing with the droplet number. While the model results for the three-pion correlation function generally agree with experimental data, there is inconsistency for the four-pion correlation function. Investigations into normalized multi-pion correlation functions show an interesting enhancement of the normalized four-pion correlation function in the moderate relative-momentum region.

Neutral current neutrino interactions at FASERν

Ahmed Ismail, Roshan Mammen Abraham, Felix Kling

Summary: FASER nu is expected to record the most energetic laboratory neutrinos ever studied, with the potential to observe neutrino neutral current scattering events. Researchers have demonstrated the use of deep neural networks to measure the neutral current scattering cross section, providing a complementary probe of neutrino nonstandard interactions to other tests such as oscillations and coherent neutrino-nucleus scattering.

Summary: This study measured the prompt production of charm baryon Lambda(c+) and the A(c)(+)/D-0 production ratios in LHC collisions, revealing a clear decrease in the Lambda(+)(c)/D-0 ratio with increasing transverse momentum in different collision systems. These results suggest that existing assumptions of parton-to-hadron fragmentation may not be sufficient to explain charm-baryon production at LHC energies.

New physics in s → d semileptonic transitions: rare hyperon vs. kaon decays

Li-Sheng Geng, Jorge Martin Camalich, Rui-Xiang Shi

Summary: We investigate the potential of rare hyperon decays to probe the short distance structure in the s -> d nu(nu) over bar and s -> dl(+)l(-) transitions. We find that the BESIII measurements of the B-1 -> B-2 nu(nu) over bar decays would lead to constraints on new physics in the purely axial vector (d) over bar gamma(mu) gamma 5s current that are stronger than the present limits from their kaon siblings K ->pi pi nu(nu) over bar. On the other hand, hyperon decays into charged leptons are dominated by long-distance hadronic contributions, but angular observable such as the leptonic forward-backward asymmetry is sensitive to the interference between long- and short-distance contributions.

Strangeness S =-2 baryon-baryon interactions and femtoscopic correlation functions in covariant chiral effective field theory

Zhi-Wei Liu, Kai-Wen Li, Li-Sheng Geng

Summary: We study baryon-baryon interactions with strangeness S = -2 using leading order covariant chiral effective field theory. We determine the relevant low energy constants by fitting to the latest HAL QCD simulations, considering all coupled channels. Comparing our calculations with experimental data for lambda lambda and (Σ0Λ)-p correlation functions, we find good agreement which demonstrates consistency between theory, experiment, and lattice QCD simulations. We also predict sigma(+)sigma, sigma(+)lambda, and sigma(+)sigma(-) interactions and their momentum correlation functions.

Summary: Rare meson decays are valuable tools for investigating both heavy and light new physics, with the use of kaons being particularly advantageous due to their small decay widths and large datasets. Hyperon decay measurements also provide complementary information. This article summarizes the relevant phenomenological models and current status of searches in both kaon and hyperon decay channels. It identifies new search strategies for unexplored signatures and highlights the potential for significant advances in exploring light dark sectors with improved sensitivities from current and future experiments.

Molecular Nature of X(3872) in B0 → K0X(3872) and B+→ K+X(3872) Decays

Hao-Nan Wang, Li-Sheng Geng, Qian Wang, Ju-Jun Xie

Summary: We study the decays of B-0 -> (KX)-X-0 (3872) and B+ -> K+X(3872) using the X(3872) resonance coupled to the D (D) over bar* + c.c channel. Besides the short-distance interaction mechanism, we also consider the long-distance rescattering diagrams of D (D) over bar*. The difference in mass thresholds and the narrow width of X(3872) at the X(3872) mass lead to significant differences in the loop functions of D (D) over bar*(0) and D+ (D) over bar*-. Taking this into account, we naturally obtain a ratio of B[B-0 -> K-0 X(3872)]/B[B+ -> K+X (3872)] similar to 0.5. Based on this result, we evaluate the decay widths of B-s(0) -> eta(eta')X(3872). Future experimental measurements of these decays are expected to provide insight into the nature of the X(3872) resonance.

Cross-Channel Constraints on Resonant Antikaon-Nucleon Scattering

Jun-Xu Lu, Li-Sheng Geng, Michael Doering, Maxim Mai

Summary: Chiral perturbation theory and its unitarized versions have been instrumental in our understanding of low-energy strong interaction. In this study, the first global analysis of meson-baryon scattering up to one-loop order is presented. The results demonstrate that covariant baryon chiral perturbation theory, including unitarization for the negative strangeness sector, can accurately describe meson-baryon scattering data. This validates the validity of this important low-energy effective field theory of QCD.

Nuclear charge radii in Bayesian neural networks revisited

Xiao-Xu Dong, Rong An, Jun-Xu Lu, Li-Sheng Geng

Summary: In this study, a refined Bayesian neural network (BNN) based approach with six inputs, including proton number, mass number, and engineered features associated with various effects, is proposed to accurately describe nuclear charge radii. The new approach shows good performance in describing charge radii of atomic nuclei with A > 40 and Z > 20, with a standard root-mean-square deviation of 0.014 fm for the training and validation data. The predicted charge radii of proton-rich and neutron-rich calcium isotopes also agree well with the data, demonstrating the reliability of the BNN approach.

Summary: This study reports on a search for light dark matter through the cascading decay of η mesons produced by the collision of cosmic rays and Earth's atmosphere. A new framework is introduced to specifically address boosted dark matter, including a dedicated simulation of both elastic and quasielastic processes of Earth's attenuation effect on dark matter particles reaching the detector. No significant excess over background is observed in the PandaX-4T commissioning data with a 0.63 tonne · year exposure. The study also provides the first constraints on the interaction between light dark matter generated in the atmosphere and nuclei through a light scalar mediator.

One-proton emission from 148-151Lu in the DRHBc plus WKB approach

Yang Xiao, Si-Zhe Xu, Ru-You Zheng, Xiang-Xiang Sun, Li-Sheng Geng, Shi-Sheng Zhang

Summary: One-proton radioactivity in 149Lu has been studied using the Wentzel-Kramers-Brillouin (WKB) approach and the proton-nucleus potential extracted from the deformed relativistic Hartree-Bogoliubov theory in continuum (DRHBc). The results show that 149Lu is oblately deformed and the predicted half-life is consistent with experimental measurements. The study also checks the validity of the approach in describing other Lu isotopes and their isomeric states, with good agreement between predicted and experimental half-lives.

New insights into the pole parameters of the Λ(1380), the Λ(1405) and the Σ(1385)

D. Sadasivan, M. Mai, M. Doring, Ulf-G. Meissner, F. Amorim, J. Klucik, Jun-Xu Lu, Li-Sheng Geng

Summary: By extending the coupled-channel S- and P-wave next-to-leading order chiral-unitary approach, we have successfully incorporated the new data from the KLOE and AMADEUS experiments as well as the Lambda pi mass distribution of the Sigma(1385) into the strangeness S = -1 meson-baryon scattering. We have calculated the positions of the poles on the second Riemann sheet corresponding to the S(1385) pole and the Lambda(1380) and Lambda(1405) poles, as well as the couplings of these states to various channels. The inclusion of KLOE and AMADEUS data has improved the average precision for determining resonance positions and branching ratios by about 20%.

Production rates of Ds plus Ds- and DD? molecules in B decays

Jia-Ming Xie, Ming-Zhu Liu, Li-Sheng Geng

Summary: Motivated by the recent discovery of the charmonium X(3960) in B decays, the possible existence of two bound/virtual states below the D+s D-s and over bar DD mass thresholds has been reexamined. Using the effective Lagrangian approach and triangle diagrams, we calculate the production rates of B+ -> Xss over bar K+ and B+ -> Xqq over bar K+ in B decays. Our results show that the production yields are consistent with experimental data, suggesting that these bound states can be detected if they do exist.

Summary: Recently, the BESIII Collaboration observed the scalar meson a0(1710)+ in the K+K0S invariant mass spectrum in the D+s -> pi 0K+K0S decay. They performed a theoretical study of a0(1710)+ in the process D+s -> pi 0a0(1710)+-> pi 0K+K0S and considered the contributions of K* and a0(980). The study supported the molecular K* over bar K* nature of the scalar a0(1710) resonance, as the recent BESIII experimental measurements can be well reproduced.

Summary: This study explores the production mechanism of charm-strange states D-s0*(2317) and D-s1(2460), and finds that the molecular model can well explain their production cross-section ratios. In addition, we predict the production yield of the three-body bound state D(D) over barK, and find that it is within the reach of the ongoing Belle II experiment.
