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.

Jet quenching in out-of-equilibrium QCD matter

This paper presents the first study of jet substructure modifications during the bottom-up evolution of out-of-equilibrium QCD matter, demonstrating that the early stages of bulk matter evolution in heavy-ion collisions leave a sizable imprint on jet radiation patterns and establishing a foundation for incorporating pre-equilibrium dynamics into realistic jet quenching models.

Producing Λ(1405)Λ(1405) and Λ(1520)Λ(1520) in πpπ^-p reaction to explore their inner structures

This study investigates the production mechanisms of Λ(1405)\Lambda(1405) and Λ(1520)\Lambda(1520) in πp\pi^- p scattering using an effective Lagrangian approach with Regge trajectories, revealing distinct dominant exchange contributions for each resonance and suggesting that Λ(1405)\Lambda(1405) possesses an exotic structure while Λ(1520)\Lambda(1520) aligns with a conventional three-quark configuration, thereby providing a theoretical basis for future high-precision experimental measurements.

Hyperon-Nucleon Spectrometer

This whitepaper proposes the Hyperon-Nucleon Spectrometer (H-NS) at the High-Intensity heavy-ion Accelerator Facility (HIAF) to systematically investigate the unresolved Λ\Lambda polarization puzzle through high-precision measurements of hyperon and proton spin observables across a wide range of collision energies and systems.

Solution of the Equation-of-Motion Phonon Method eigenvalue problems on the D-Wave quantum annealer

This paper presents a hybrid quantum-classical algorithm combining quantum annealing and classical deflation to iteratively solve large-scale eigenvalue problems from the Equation-of-Motion Phonon Method on D-Wave quantum hardware, demonstrating both the potential and current limitations of near-term quantum devices for nuclear many-body theory.

Mechanical distribution of the pseudoscalar charmonium and bottomonium on the light-front

This paper investigates the mechanical properties of pseudoscalar charmonium and bottomonium within the light-front quark model by evaluating gravitational form factors and analyzing their spatial distributions, revealing that while most properties are sensitive to wave function choices near the meson's center, the pressure distribution exhibits a sign-changing node and the force distribution remains positive to support stability.

External-Field-Assisted Muon Reactivation in Muon-Catalyzed Fusion: A Rate-Network Criterion for Reducing Alpha Sticking

This paper proposes a rate-network framework to evaluate external-field-assisted reactivation for reducing alpha sticking in muon-catalyzed fusion, demonstrating that while such methods can theoretically increase cycle yield from 112.6 to 156.5, their success is strictly constrained by a probabilistic no-go condition requiring efficient muon confinement and recycling within a specific transport window.
