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.

Investigation of hadronic effects on resonance productions in small collision systems using the EPOS4 model

This study utilizes the EPOS4 model to demonstrate that hadronic interactions, specifically the competition between rescattering and regeneration, significantly modify resonance production yields and distributions in both small (pp, p-O) and large (O-O, Pb-Pb) collision systems at LHC energies, highlighting the critical role of the hadronic phase even in small systems.

Extracting nuclear charge radii from binding energies: a single-parameter empirical formula with structural corrections

This paper proposes a novel one-parameter empirical formula, BECR1p_{1p}, which leverages binding energy correlations and structural corrections to accurately model nuclear charge radii, achieving a root-mean-square deviation of 0.0138 fm on experimental data and enabling predictions for over 11,000 nuclei.

Next-to-next-to-leading order QCD corrections to pion (kaon)-induced exclusive Drell-Yan process

This paper calculates substantial and positive next-to-next-to-leading order (NNLO) QCD corrections for pion- and kaon-induced exclusive Drell-Yan processes within the generalized parton distribution framework, establishing the necessity of including these higher-order effects for reliable theoretical predictions to match future J-PARC experimental data.

Neural-Accelerated Bayesian Calibration of Chiral Mean-Field Models to Nuclear Saturation and Vacuum Properties

This paper presents a neural-accelerated Bayesian inference framework that efficiently calibrates chiral mean-field models to nuclear and vacuum constraints, revealing that while viable parameter regions are rare, the resulting degeneracies imply that distinct models can yield qualitatively different predictions for dense matter and neutron stars, underscoring the necessity of combining terrestrial and astrophysical data.

Lorentz-Covariant Spectral Bounds from Thermal Quantum Field Theory: Retarded Green's Functions, Kubo Relations, and Holographic Constraints

This paper establishes rigorous, frame-dependent Lorentz-covariant bounds on the spectral singularities and hydrodynamic convergence of thermal quantum field theories by combining analyticity, positivity, and KMS conditions, a framework that is explicitly verified and refined through holographic quasinormal mode calculations.

Nuclear Charge Radius of 9^9Be from Muonic Atom Spectroscopy Using a Microcalorimeter

Using a metallic magnetic calorimeter to measure the 2p→1s2p\to1s transition energy in muonic 9^9Be with unprecedented precision, this study determines a nuclear charge radius of 2.5506(51) fm that is significantly more accurate than previous values and marks the first such determination via muonic x-ray spectroscopy with microcalorimeters.

Evidence for sequential Υ\Upsilon(nS) suppression in light ion collisions

This paper presents the first measurements of Υ\Upsilon(1S), Υ\Upsilon(2S), and Υ\Upsilon(3S) production in oxygen-oxygen and neon-neon collisions at sNN\sqrt{s_\mathrm{NN}} = 5.36 TeV, revealing a significant sequential suppression pattern where excited states are more strongly suppressed than the ground state, providing evidence for quark-gluon plasma formation in light ion collisions.

Towards compressed baryonic matter densities: D meson diffusion

This paper investigates the spatial diffusion and momentum transport coefficients of D mesons in dense nuclear matter using a chiral SU(3) hadronic model and kinetic theory, revealing that these properties decrease rapidly at low densities and more mildly at high densities, offering insights relevant to future heavy-ion collision experiments.

Using γ\gamma+jets to quantify medium-induced jet broadening in heavy-ion collisions

Using the JEWEL event generator, this study proposes a strategy to mitigate selection bias in heavy-ion collisions by re-clustering small-radius jets into "trimmed" jets, demonstrating that while this approach recovers some medium-induced broadening signals, the full effect is best observed by analyzing the radial profiles of sub-leading subjets beyond their cone radii.

Entangling Power and Symmetries in the Quantum Rabi Model

This paper demonstrates that time-averaged entangling power serves as an effective operator-level diagnostic for distinguishing between manifest U(1)U(1) symmetry and parameter-dependent hidden symmetries in the Quantum Rabi model family, revealing distinct spectral responses such as peaks at integer-bias points for the asymmetric model and dips for the Jaynes-Cummings limit.
