Abstract

We investigate the longitudinal momentum distributions (LMDs) of the deuteron using a relativistic deuteron wave function derived from a realistic nucleon-nucleon (NN) interaction within the light-front framework. By convoluting the deuteron LMDs with the nucleon parton distribution functions (PDFs), we analyze the unpolarized, longitudinally polarized, and tensor-polarized structure functions of the deuteron. In addition, we also study the EMC effect in the weakly bound deuteron through the structure function ratio $F_{2}^{D}/(F_{2}^{p}+F_{2}^{n})$, which deviates from unity due to nuclear binding and Fermi motion effects.

Impacts of isolated nucleon-nucleon correlations in relativistic $^{16}$O+$^{16}$O collisions

Nucleon-nucleon (NN) correlations in nuclear ground states can leave measurable imprints on the initial geometry of relativistic light-ion collisions. We introduce an Acceptance-Rejection Method (ARM) that provides a controlled framework for assessing the effects of selected two-body spatial correlations while keeping the underlying one-body radial density fixed. Starting from a common three-parameter Fermi (3pF) radial profile, we construct ensembles that separately incorporate pair-distance correlations ($\mathrm{ARM}_r$) and pairwise angular correlations ($\mathrm{ARM}_θ$), and compare them with $^{16}\mathrm{O}$ configurations generated by Variational Monte Carlo (VMC) and Nuclear Lattice Effective Field Theory (NLEFT). We find that radial pair-distance correlations largely determine the bulk scale of initial-state geometric fluctuations, while angular correlations provide additional information required to reproduce eccentricity--energy covariance observables. The remaining small differences between the full many-body configurations and $\mathrm{ARM}_θ$ indicate contributions from higher-order many-body correlations not encoded by two-body constraints alone. These results demonstrate how controlled correlation sampling can quantify the impact of nuclear many-body structure on initial-state observables in relativistic light-ion collisions.

Momentum Distributions and Spatial Signatures of Proton Halos in the sd Shell

We perform a theoretical study of intermediate-energy quasifree one-proton knockout reactions on proton targets. Single-particle wave functions constrained by the experimental proton separation energies are employed to calculate longitudinal momentum distributions, one-proton removal cross sections, and full momentum-space profiles for $^{26}$P, $^{27}$S and $^{31}$Ar nuclei. To establish robust criteria to identify proton halos, the analysis is extended beyond the traditional momentum-width approach by investigating the spatial extension of the valence proton through root-mean-square radii and the probability that the proton resides outside the core nucleus, $P(r>R_{\rm core})$. We also examine Coulomb-barrier systematics, mirror-nucleus comparisons, realistic spectroscopic mixtures, finite experimental momentum resolution, and uncertainties associated with the proton separation energy. Our calculations indicate that proton-halo structure cannot be identified reliably from a single observable. A consistent interpretation emerges only when momentum distributions, spatial observables, Coulomb effects, and many-body structure are considered simultaneously. Within the present model, $^{26}$P exhibits the strongest proton-halo signatures, while $^{27}$S retains pronounced halo-like features despite its larger Coulomb barrier. The more strongly confined $^{31}$Ar provides a useful comparison and illustrates the progressive suppression of halo observables with increasing binding and core charge.

Influence of nuclear matter properties on heavy-ion sub-barrier fusion reactions

Interactions between two nuclei in nuclear reactions are calculated by applying the energy density method to nuclear energy density functionals. We particularly focus on the effects of nuclear mat- ter properties on fusion reactions by using the Korea-IBS-Daegu-SKKU (KIDS) density functional. Uncertainty of the equation of state in symmetric nuclear matter is accounted for by using different values of the incompressibility and the effect is explored with the 40Ca+40Ca system. Though not prominent, a systematic dependence on the incompressibility can be inferred from the fusion cross sections. The effect of asymmetric nuclear matter is described by adopting the symmetry energy parameters that are consistent with the neutron star data, but still have large uncertainties. In the application to the 48Ca+48Ca and 16O+208Pb systems, we observe a systematic dependence on the stiffness of the symmetry energy. We also consider the uncertainty of the effective mass of the nucleon in nuclear medium. We employ models that have isoscalar and isovector effective masses varying from minimum to maximum values in the allowed ranges. Contrary to incompressibility and symmetry energy, fusion cross sections are insensitive to the isoscalar and isovector effective masses. Without any phenomenological adjustment or modification of the model, fusion processes are described accurately by applying the interaction potentials derived from nuclear structure mod- els
