Summary: This study presents precise measurements of the cross sections and spin observables of the elastic H-2(d, d)d scattering process at intermediate energies. The results, obtained using a polarized 130 MeV deuteron beam, provide valuable data for confronting upcoming state-of-the-art calculations in four-nucleon scattering. The data from two independent setups at the AGOR facility at KVI show excellent agreement, allowing for a thorough systematic analysis to offer the most accurate insights into the dynamics of three and four-nucleon forces in few-nucleon systems.

Summary: In this paper, we generalize Weinberg's compositeness relations by including the range corrections and provide an analytic expression for the form factor. We establish an exact relation between the wave function of a bound state and the phase of the scattering amplitude. The deuteron is used as an example to illustrate the formalism, which can be applied to other cases where range corrections are important.

Summary: The experimental data of various nucleon transfer reactions and elastic/inelastic scattering for deuteron energy of 14.5 MeV were analyzed using CDCC and CRC methods. The CDCC calculations accurately described the elastic scattering at forward angles, including the deuteron breakup, while backward angles were influenced by target excitation and neutron-transfer reactions. The excitation of 11B and the neutron pickup reaction had the strongest effects, while the proton-transfer reactions were negligible.

Summary: In this study, vector analyzing powers for the d((p)over-right-arrow, pp)n reaction were measured using a polarized proton beam. The results showed that theoretical models were unable to accurately reproduce experimental data at very low relative energies. The findings serve as a basis for future investigations of spin-isospin dependencies in the nuclear many-body force.

Summary: In this paper, the full quantum mechanical model of inclusive breakup is applied to heavy radioactive nuclei reactions on a Be-9 target at intermediate energies. Comparisons are made with the semiclassical transfer to the continuum model to gain insight into the complex heavy-ion reactions. The results show good agreement between the calculated results of both methods and available experimental data, indicating a comprehensive understanding of one nucleon breakup process.

Summary: The purpose of this study is to introduce the 3N force into the dynamic part of the OP for a more consistent calculation. Through an approximate treatment of the 3N force in the model, the major contribution of the two-pion exchange term to the 3N force is identified, and the convergence of results at the next-to-next-to-next-to-leading-order is confirmed.

Summary: Faddeev calculations with the incorporation of a 2 pi-exchange Lambda NN three-baryon force are performed to determine the separation energy of hypertriton, H-3(A). Repulsive contributions of the three-baryon force, on the order of 20 keV, are found depending on the NN interactions used. This effect is significant compared to the small separation energy of H-3(A).

Summary: In this study, the differential cross-section of deuteron-deuteron elastic scattering is calculated at various momenta, taking into account the D-state and three-nucleon force effect. The results show that the inclusion of three-nucleon force is necessary to improve the agreement with experimental data at higher momentum transfers.

Summary: In this study, the experimental measurements of deuteron-deuteron elastic scattering differential cross-section are well described using the Glauber multiple scattering theory with the inclusion of the three-nucleon force. The three-nucleon force has a negligible effect at low momenta, where the two-nucleon force is sufficient to explain the experimental data. However, at medium energy, the three-nucleon force starts to have a noticeable impact. At the intersecting storage rings energy, the effect of the three-nucleon force is observed prominently at the minimum of the differential cross-section, while it is generally small for other values of momentum transfer squared.

Summary: The differential cross sections of the Sigma(-) p -> Lambda n reaction were accurately measured and precise angular information about the reaction was obtained for the first time. The obtained differential cross sections show a slightly forward-peaking structure. These results play an essential role in updating the theoretical models of baryon-baryon interactions.

Summary: The effective interaction between a nucleon and a nucleus is crucial for reaction theories. Recently, the calculation of the leading order term in the Watson multiple scattering approach has been achieved ab initio, allowing for systematic exploration of uncertainties in nucleon-nucleus elastic scattering observables. This study focuses on the calculation of the leading order nucleon-nucleus interaction using a specific chiral NN interaction and light nuclei with a 0(+) ground state, and analyzes elastic scattering observables for He-4, C-12, and O-16 projectiles with energies between 65 and 200 MeV.

Summary: We introduce a new analysis on the distribution of partons, including new data on the production of W boson and lepton pairs in proton-proton and proton-deuteron collisions. The new data provide strong constraints on the distribution of light antiquark partons in the proton. We discover an interesting correlation between the d/u ratio and the d over bar /u over bar ratio, leading to modifications of our previous results for the d/u ratio at high parton momentum fractions.

Summary: A kinematically complete quasifree (p, pn) experiment in inverse kinematics was performed to study the structure of the Borromean nucleus B-17, revealing a definite but not dominant neutron halo. Our finding of a surprisingly small 1s(1/2) percentage and the explanation using the deformed relativistic Hartree-Bogoliubov theory in continuum implies that the dominant occupation of s or p orbitals is not a prerequisite for the occurrence of a neutron halo.

Summary: The nuclear structure of Ar-51 was studied using gamma-ray spectroscopy and the invariant mass method, revealing two bound and six unbound states. The low cross sections of the two bound states were interpreted as a clear signature of significant subshell closures at neutron numbers 32 and 34 in argon isotopes. Additionally, it was found that unbound collective states coexist with individual-particle states in Ar-51 due to the presence of two valence holes.

Summary: In this study, a full symmetrizer (antisymmetrizer) S-N for a system of N identical bosons (fermions) is defined, which can be built recursively as a product of simple permutation operators. The N-body Faddeev equation is rewritten using this form of S-N, which significantly simplifies the process of building the N-body wave function. This formulation can be extended to include three- and other many-body forces.

Summary: In this study, we constructed a folding potential between alpha and Lambda particles and analyzed the binding energy of He-5(Lambda) using different potential models. The experimental results are consistent with the predictions of the folding potential model within the error range, but the calculations using realistic potentials result in overbinding.

Summary: Experimental observations on different isotopes Ca-55, Ca-57 have revealed important phenomena in their states, which are consistent with theoretical calculations. The existence of a short-lived state in Ca-57 suggests a transition in the calcium isotopic chain from single-particle dominated states at N = 35 to collective excitations at N = 37.

Summary: This article discusses the long-standing question in nuclear physics of whether chargeless nuclear systems can exist. The researchers report on the observation of a resonance-like structure in the four-neutron system, indicating the existence of a quasi-bound tetraneutron state for a very short time. The measured energy and width of this state serve as an important benchmark for understanding the nuclear force.

Summary: An indirect method based on timestamp analysis is developed to estimate the deadtime of a data acquisition system. The method's effectiveness is verified by studying the performance of different types of time-to-digital converter modules. The data acquisition system of the SAMURAI spectrometer at the RIKEN radioactive isotope beam factory is optimized using this method, resulting in a significant reduction in event deadtime.

Summary: We have developed a relativistic model that allows for calculations of cross sections and polarization observables in electron and neutrino scattering experiments with deuteron targets. The dynamics of strong interactions are described by a unitary representation of the Poincare group, with the same representations for space translations and rotations in both interacting and noninteracting states. Our model uses the Argonne V18 potential to reproduce experimental observables for deuteron binding energy and nucleon-nucleon scattering. It is applicable to processes where the internal energy of two nucleons is below the threshold for pion production, but the momentum transfer extends to several GeV.

Summary: A hyperon-nucleon potential for the S = -1 sector up to third order in the chiral expansion is introduced, considering both the SU(3) flavor symmetry and explicit SU(3) symmetry breaking. An innovative regularization scheme is used, leading to an excellent description of scattering data and the analysis of new data from J-PARC. Results for hypertriton and A = 4 hyper-nuclear separation energies are presented, along with an uncertainty estimate for selected observables in the hyperon-nucleon system.

Summary: This paper presents a comprehensive investigation on few-nucleon systems as well as light and medium-mass nuclei, using the current Low Energy Nuclear Physics International Collaboration two-nucleon interactions and three-nucleon forces. By considering higher-order corrections and performing correlated truncation error analysis, the resulting Hamiltonian is shown to successfully predict various observables and spectra of nucleon-deuteron scattering and light p-shell nuclei. However, the charge radii are found to be underpredicted by approximately 10% for the oxygen isotopes and almost 20% for 40Ca and 48Ca.

Summary: In this study, absorption reactions are investigated using single-nucleon and two-nucleon transition operators derived from chiral effective field theory. The results show that the absorption rates strongly depend on the nuclear pion absorption operator used and the two-body parts of the operator significantly affect the rates. The final state interactions between nucleons generated by two-nucleon forces are important, while the three-nucleon interaction plays a visible role only in certain reactions.
