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 proposes a universal, concise, and extensible "ABC" naming scheme to classify light exotic nuclei () based on their distinct structural properties such as halos, Borromean configurations, and clusterisation.
This paper investigates the observed shift of the resonance peak in pion-proton femtoscopic correlations by applying a T-matrix approach within the Koonin-Pratt framework to reveal how the finite emission source induces off-shell dynamics, though the model's inability to fully reproduce experimental correlation strength and the absence of a predicted high-momentum dip suggest the need for more complex source descriptions beyond a simple spherical Gaussian approximation.
This paper proposes a perturbative method for calculating bound states in QED and QCD using canonical quantization in the temporal gauge, demonstrating how instantaneous potentials arise from Gauss' law constraints to enable perturbative hadron calculations and explain spontaneous chiral symmetry breaking.
This paper introduces a Physics-Informed Neural Ensemble (PINE) model utilizing a Hierarchical Residual Decomposition framework to systematically filter chaotic many-body signatures from nuclear mass residuals, demonstrating that hierarchical neural learning can suppress quantum-chaotic spectral rigidity and drive deviations toward an uncorrelated white-noise limit.
This paper presents a generalized Brownian motion model consistent with the GKSL equation to derive an analytical expression for steady-state heat flow that satisfies Fourier's law and captures thermal boundary resistance, while also revealing unique transient heat current behaviors and continuous, nowhere-differentiable trajectories that distinguish it from standard models.
This paper presents a microscopic analysis of the decay of Ge, revealing that the nuclear matrix element converges at excitation energies below 5 MeV due to the cancellation of fragmented high-lying states and is further reduced by approximately 10% due to two-body current effects.
This paper presents a systematic theoretical study using the microscopic projected shell model to calculate bound-state decay half-lives for hundreds of nuclei, identifying seven specific highly ionized candidates with significantly shortened half-lives that are promising targets for future storage-ring experiments and astrophysical modeling.
This paper presents a theoretical study using the TRENTo3D and CLVisc models with a novel initial longitudinal flow gradient to simultaneously describe STAR's global and azimuthal hyperon polarization measurements in isobaric Zr+Zr collisions, revealing that the azimuthal modulation is dominantly driven by shear effects while highlighting the challenges in achieving a unified description of all polarization observables.
This paper predicts the existence of ten narrow, isoscalar five-flavor () molecular pentaquark states in the 7.72–7.96 GeV range, along with two additional deeply bound states, by applying local hidden gauge and heavy-quark symmetries to meson-baryon interactions, thereby extending previous hidden-charm studies to the bottom sector and offering specific targets for LHCb searches.
This paper presents global Bayesian limits on Majorana neutrino masses by combining latest neutrinoless double-beta decay experimental data with ab initio nuclear matrix elements, revealing that current experiments likely lack the sensitivity to probe the neutrino mass regime allowed by oscillation data while demonstrating that next-generation searches across four key isotopes could collectively cover the inverted mass ordering.
