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.

Proton-proton Femtoscopy as a Probe of Short-range Structure in High-Energy O+O Collisions

This paper demonstrates that proton-proton femtoscopy in high-energy O+O collisions serves as a sensitive probe of short-range nucleon-nucleon correlations, effectively distinguishing between different nuclear structure models and revealing sub-femtometer details that are invisible to traditional size measurements or pion correlations.

What are the consequences of independent factorization and renormalization scales?

The paper argues that simultaneously preserving renormalization group invariance, Ward identities, and parton density sum rules in QCD factorization theorems necessitates that independent factorization and renormalization scales must be equal, with significant implications for phenomenological scale sensitivity, global QCD analyses, and connections to lattice QCD.

Quantum Simulation of Nuclear Shell Model Using GCM-Based Methods on NISQ Devices

This paper demonstrates a robust and scalable approach for simulating low-lying nuclear eigenstates on noisy intermediate-scale quantum (NISQ) devices by employing a hybrid quantum-classical Generator Coordinate Method (QuGCM) enhanced with an adaptive selection strategy (ADAPT-GCIM) and optimized Gray code encoding, achieving accurate energy spectra for systems like the deuteron, 6^6Li, and 38^{38}Ar that align with classical results despite hardware limitations.

Diffusion and shear viscosity coefficients of hot isospin asymmetric strange hadronic matter using a chiral SU(3) model

Using a chiral SU(3) model and the Chapman-Enskog expansion, this study calculates the diffusion and shear viscosity coefficients of hot isospin asymmetric strange hadronic matter, revealing that finite strangeness significantly enhances shear viscosity while isospin asymmetry strongly influences diffusion coefficients but has only a marginal effect on shear viscosity.

Probing Quadruple Deformation in Transitional Nuclei via Angular Momentum Projection

This paper utilizes angular momentum projection within the interacting boson model to demonstrate that KK-mixing is negligible in transitional nuclei and reveals that increasing angular momentum stretches quadrupole deformation, offering a geometric explanation for Jacobi-type transitions and low-spin B(E2)B(E2) anomalies in nuclei such as 160^{160}Gd, 162^{162}Dy, and 170^{170}Os.

The (2+1)(2+1)-dimensional Gross-Neveu-Yukawa model at finite temperature, density, and magnetic field within the Functional Renormalization Group

Using the Functional Renormalization Group with a hydrodynamical algorithm, this study investigates the (2+1)-dimensional Gross-Neveu-Yukawa model at finite temperature, density, and magnetic field, revealing that strong magnetic fields induce magnetic catalysis and dimensional reduction while weak fields at high chemical potential produce de Haas–van Alphen oscillations and multiple first-order phase transitions alongside a shifting critical endpoint.

Effects of light-cluster degrees of freedom on collective flows in heavy-ion collisions at FOPI energies

Using a lattice Boltzmann-Uehling-Uhlenbeck transport model with a kinetic approach for light-cluster formation, this study demonstrates that explicitly including dynamical light-cluster degrees of freedom significantly modifies proton collective flows at beam energies below 600 A MeV and successfully reproduces the nucleon-number scaling of light nuclei flows, thereby highlighting the necessity of dynamical cluster treatment for interpreting heavy-ion collision data in this energy regime.
