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.
Using transverse-momentum-dependent QCD factorization, this paper demonstrates that jet-induced anisotropy at the Electron-Ion Collider imposes a parity selection rule on polarized asymmetries, fundamentally altering the expected left-right and up-down symmetries of structure functions like the Sivers and worm-gear distributions across different harmonic orders.
This paper employs the Parton-Hadron-String Dynamics (PHSD) transport approach combined with the Remler formalism to validate a consistent description of charmonium production in pp and pA collisions at SPS energies and provides theoretical predictions for yields and survival probabilities at FAIR energies, offering crucial guidance for mapping the QCD phase structure in baryon-rich matter.
This paper introduces NS-UNO, a flexible Neural Posterior Estimation framework that combines hierarchical DeepSets and conditional normalizing flows to infer the neutron star equation of state from an unconstrained number of mass-radius observations, demonstrating robust performance across varying dataset sizes, precisions, and equation-of-state families.
This paper presents an impact-parameter dependent perturbative QCD model based on the Color Glass Condensate framework, which successfully describes a wide range of combined HERA data at small- by incorporating an analytical solution to the Balitsky-Kovchegov equation and an exponential saturation momentum profile consistent with the Froissart theorem.
This paper advances a modified homotopy approach for solving the nonlinear evolution equation governing diffractive production in deep inelastic scattering by analytically solving a simplified version with initial and boundary conditions and then applying a perturbative procedure to estimate the remaining small nonlinear corrections.
This paper reviews a modified homotopic approach that analytically solves a simplified non-linear evolution equation for diffractive production in deep inelastic scattering by incorporating specific non-linear corrections into the linear term, finding that these corrections are small enough to be estimated via a regular iterative procedure.
This paper proposes a homotopy approach to analytically solve the nonlinear Balitsky-Kovchegov evolution equation with a running QCD coupling, demonstrating that the first iteration achieves high accuracy for the leading twist kernel while also analyzing geometric scaling and infrared cutoff dependencies.
This paper presents the first complete resource characterization for simulating nuclear dynamics using a first-quantized Leading Order pionless EFT Hamiltonian, demonstrating that polynomial-time evolution is achievable with early fault-tolerant quantum computers and offering an exponential improvement over previous second-quantization approaches.
This paper presents a full-coupling Feshbach theory approach within the CDCC framework to derive an explicit non-local dynamic polarization potential for nuclear optical models, which successfully reproduces elastic scattering data for Ni and quantifies the distinct energy-dependent roles of virtual breakup and continuum absorption in elastic flux loss.
This paper computes high-frequency gravitational wave radiation from collisions between light and heavy compact objects using shockwave propagators, revealing a perturbative expansion of tidal response functions that connect Lipatov vertex amplitudes to Weinberg's soft radiation limits while highlighting double-copy structures with Yang-Mills gluon radiation.
