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 introduces simple boundary corrections to the matrix Numerov method that incorporate analytic near-origin information, thereby restoring and even enhancing its convergence order for solving the Schrödinger equation with singular potentials like the Coulomb interaction.
This paper applies Time-Dependent Hartree-Fock theory to investigate fusion and quasifission dynamics in heavy-ion reactions relevant to superheavy element production, demonstrating reasonable agreement with experimental data for Ca+U fusion and revealing the significant impact of tensor forces on shell effects in Ca+Bk quasifission.
This paper demonstrates that a joint Bayesian calibration of low- bulk observables and high- tomographic data significantly tightens constraints on Quark-Gluon Plasma properties and resolves discrepancies in high- anisotropy predictions that arise when using low- data alone.
This paper synthesizes new threshold measurements of production from JLab experiments (007 and CLAS12) with previous GlueX data to confirm a consistent phenomenological determination of the -proton scattering length, while highlighting how upcoming J-PARC measurements will further clarify the systematic trend of vector meson-nucleon interactions predicted by the "young vector meson" hypothesis.
This paper utilizes a three-quark light-front model to calculate the gluon Sivers function of a proton at moderately small and numerically determines its small- evolution via the BFKL anomalous dimension, revealing a power-law tail behavior of at high transverse momentum.
This paper extracts the speed of sound in the quark-gluon plasma from ATLAS transverse momentum fluctuation data in ultra-central Pb+Pb collisions by correcting for detection biases and hadronization noise, yielding a result of that aligns perfectly with first-principles lattice QCD calculations.
This paper utilizes a modified HIJING Monte Carlo generator to demonstrate that event-by-event multiplicity fluctuations serve as a sensitive diagnostic tool for distinguishing between hot and cold media, validating energy loss models, and identifying signatures of a first-order phase transition in relativistic heavy-ion collisions.
This paper introduces the Cooperative Neural Network (CoNN), a baseline-free architecture that embeds physical priors directly into its structure to predict nuclear binding energies with high accuracy using only proton and neutron numbers, effectively replacing the need for hand-crafted physics features or theoretical baselines.
This paper presents a comprehensive overview of recent ALICE measurements from Run 2 and Run 3 on photon-induced processes in ultra-peripheral collisions, covering exclusive vector meson photoproduction, nuclear breakup mechanisms, and inclusive photonuclear interactions to probe gluon saturation, quantum interference, and particle production dynamics in nuclear environments.
This paper investigates the energy loss of high-energy partons in anisotropic plasmas within the harmonic approximation, deriving a simple formula for the impact of anisotropy and demonstrating that the resulting medium length dependence exhibits universal limiting attractor characteristics consistent with QCD kinetic theory simulations.
