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 investigates how the extreme tidal gradients of asteroid-mass primordial black holes can gravitationally ionize atoms, dissociate deuterons, and induce nuclear fission, proposing these unique phenomena as potential observational signatures to distinguish such black holes from other dark matter candidates across various cosmological epochs.
This paper utilizes the Krasnosel'skii-Guo Cone Compression Theorem and a hybrid fixed point approach to prove the existence of continuous, decreasing Nambu solutions to the rainbow-ladder gap equation in QCD for all positive quark masses and a broad class of interaction kernels.
This paper establishes a non-perturbative Green's function formalism that models sub-barrier proton-nucleus scattering via a surface delta-shell impurity, successfully predicting resonance energies for , , and systems while distinguishing between weak-coupling threshold states and saturated geometric plateau states.
This paper introduces a new parametrization for N-point energy correlators that enables the derivation of a general factorization theorem in the back-to-back limit and the analytic determination of leading non-perturbative power corrections for arbitrary N, including non-integer values, thereby facilitating future precision extractions of the strong coupling constant.
This paper proposes that existing ultra-clean underground NaI dark matter detectors can search for galactic axions produced by carbon-burning stars via resonant absorption of 440 keV axions, potentially probing axion-nucleon couplings in a parameter space that remains viable despite existing astrophysical constraints.
This study resolves a long-standing discrepancy in the to transition strength of Fe by using Coulomb-excitation measurements to demonstrate that previous lifetime data were overestimated due to outdated electronic stopping power models, thereby confirming the validity of shell-model predictions.
This paper introduces a novel algebraic modeling strategy for pion Generalized Parton Distributions that rigorously satisfies all QCD constraints, demonstrating through next-to-leading order calculations that gluons dominate the pion's response in deeply virtual Compton scattering at Electron Ion Collider kinematics.
This paper employs a Poincaré-covariant Dyson–Schwinger–Bethe–Salpeter framework to demonstrate that, despite the top quark's rapid weak decay, quantum chromodynamics predicts the existence of tightly correlated pseudoscalar and vector toponium bound states with masses near 345 GeV and minimal hyperfine splittings.
This paper investigates inclusive heavy meson ( and ) photoproduction in ultraperipheral $pPb$ and $PbPb$ collisions at LHC energies using the color dipole formalism with various unintegrated gluon distribution models, presenting first-time predictions for mesons and demonstrating that future experimental data will significantly constrain high-energy hadronic structure descriptions.
This paper introduces ALPHANSO, an open-source Python package that modernizes (,n) neutron source term calculations by incorporating updated nuclear data and offering a modular framework that matches or exceeds the accuracy of legacy tools like SOURCES-4C.
