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.

Valence quark distribution of the pion inside a medium with finite baryon density: A Nambu--Jona-Lasinio model approach

This paper employs a two-flavor Nambu--Jona-Lasinio model coupled with a light-cone quark model to calculate and analyze the in-medium valence quark distribution, electromagnetic form factor, and distribution amplitude of the pion at finite baryon density, comparing the resulting parton distribution functions and their Mellin moments with experimental data, lattice QCD, and theoretical predictions after NLO DGLAP evolution.

Intertwined quantum phase transitions in the even-even $^{90-100}$ Sr isotopes

Using the interacting boson model with configuration mixing, this study identifies the even-even $^{90-100}$ Sr isotopes as a region of intertwined quantum phase transitions where a crossing between normal and intruder configurations coincides with a shape evolution within the intruder configuration, a scenario strongly supported by comprehensive comparisons with experimental data.

Coulomb bridge mechanism for peripheral polarization of weakly bound projectiles

This paper identifies the Coulomb bridge mechanism as the dominant driver of peripheral polarization in weakly bound halo projectiles, demonstrating through a decomposed Feshbach dynamical polarization potential that Coulomb-mediated P-Q couplings are essential for breakup-induced absorption in high-angular-momentum reactions.

Universal characterization of Efimovian $D^0 nn$ System via Faddeev Techniques

Using leading-order Faddeev techniques in the zero-coupling limit, this study demonstrates that the $D^0nn$ system exhibits universal Efimovian halo-bound characteristics, where ground state properties are rendered regulator-independent through the inclusion of a three-body force.

Uncertainty Quantification of the $^{76}$ Ge Neutrinoless Double-Beta Decay Nuclear Matrix Element

This paper quantifies the theoretical uncertainty of the neutrinoless double-beta decay nuclear matrix element for $^{76}$ Ge by applying a rigorous statistical protocol with bounded fluctuations to effective interactions and Bayesian Model Averaging, yielding a central value of 2.46 with a standard deviation of 0.25.

Bootstrapping Two-Nucleon Effective Field Theories

This paper employs bootstrap techniques to demonstrate that both contact-term renormalization and the exact N/D method yield statistically consistent two-nucleon effective field theories, with the NLO potential significantly extending the valid energy range compared to LO when applied to the $^1S_0$ partial wave.

Universality of the chiral soliton lattice and its interaction with quark matter

This paper establishes the universality of the chiral soliton lattice (ChSL) as a robust low-energy feature of QCD coupled to electromagnetism, demonstrating its stability against higher-order corrections and deriving the exact analytical spectrum of fermionic excitations to characterize its interaction with quark matter.

Low-energy enhancement in the magnetic dipole radiation of actinide nuclei

This paper presents the first theoretical evidence, using the shell-model Monte Carlo method, that a low-energy enhancement in the magnetic dipole $\gamma$ -ray strength function persists in actinide nuclei alongside a scissors mode resonance.
