Nuclear theory sits at the fascinating intersection of particle physics and the forces that hold our universe together. This field explores how protons and neutrons bind inside atomic nuclei, seeking to understand the fundamental interactions that govern matter at its most dense and energetic levels. While the mathematics involved can be incredibly complex, the core questions are deeply human: how does the universe function at its smallest scales, and what happens when we push matter to its limits?
At Gist.Science, we make these cutting-edge discoveries accessible by processing every new preprint published in this category on arXiv. Our team transforms dense academic manuscripts into clear, plain-language summaries alongside detailed technical overviews, ensuring that both experts and curious readers can grasp the latest breakthroughs without getting lost in the jargon. Below are the latest papers in nuclear theory, distilled and ready for you to explore.
This paper constructs the non-derivative four-point contact interactions for octet and decuplet baryons in SU(3) Chiral Effective Field Theory up to Next-to-Leading Order, utilizing the expansion to reduce the number of independent Low-Energy Constants from 134 to 24 and deriving sum rules for and scattering to be tested by future lattice QCD results.
This study employs relativistic coupled-cluster theory to demonstrate the critical importance of triple excitations in accurately determining the electric dipole polarizabilities and quadrupole moments of clock states in singly charged alkaline-earth metal ions (Ca, Sr, and Ba), while also deriving nuclear quadrupole moments that reveal significant deviations from existing literature values.
This paper introduces ToMCCA-3, a realistic three-body coalescence model based on the Wigner function formalism and constrained by modern nuclear interaction data, which successfully predicts light (anti)nuclei yields in proton-proton collisions at 13 TeV and demonstrates their sensitivity to nuclear wave functions when compared with ALICE experimental data.
This paper demonstrates a remarkable convergence between Basis Light-Front Quantization and Dyson-Schwinger equations in predicting charmonium light-front wave functions and associated observables, thereby validating both Hamiltonian and Lagrangian approaches for studying non-perturbative QCD structure.
This paper investigates the feasibility of extracting baryon-antibaryon generalized distribution amplitudes from the process using QCD factorization and numerical estimates, demonstrating that such a measurement is achievable at the Belle II experiment.
This study investigates the structural effects of , , and mesons on Be nuclei using HAL QCD potentials and the Gaussian expansion method, revealing that the meson strongly binds the system into stable states while and interactions are weaker and form only shallow bound states, with specific predictions for new -charmonium bound states and the non-Borromean nature of .
This paper proposes using Noether's second theorem, rather than the first, to derive unique and physically consistent energy-momentum and spin currents for free massive Dirac particles, thereby resolving the ambiguities typically associated with pseudogauge transformations in relativistic spin hydrodynamics.
This paper utilizes the norm operator method to demonstrate that subspace mappings in boson expansion theory can be properly derived from whole space mappings through the appropriate renormalization of non-adopted phonon contributions, thereby correcting conventional misconceptions and validating the Park operator's effectiveness in subspace contexts.
This paper proposes a nuclear molecule model for heavy nuclei composed of two interacting heavy nuclei, deriving a Hamiltonian to analytically and numerically describe roto-vibrational excitations in Pu and predict hyperdeformed states in Th, while also analyzing fission fragment angular distributions.
This paper investigates the far-from-equilibrium dynamics of a relativistic massive gas with various quantum statistics undergoing Bjorken expansion using the method of moments, revealing that the trace anomaly and bulk viscosity exhibit non-monotonic time evolution, depend sensitively on particle statistics and initial chemical potential, and converge to a universal late-time attractor regardless of initial non-equilibrium configurations.
