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 presents a parameter-free dispersive analysis of the decay using a coupled-channel Muskhelishvili-Omnès framework, which successfully fits experimental data and validates the consistency of the underlying formalism across scattering, fusion, and radiative decay processes.
This paper demonstrates that moderate orbital eccentricity in binary neutron star systems significantly enhances the detectability of g-mode dynamical tides with current gravitational-wave detectors by amplifying phase shifts through higher eccentric harmonics and epicyclic resonances, thereby enabling robust constraints on neutron star composition.
This paper derives a systematic, gauge-invariant operator framework for back-to-back dijet production in deep inelastic scattering at arbitrary Bjorken-x to twist-3 accuracy, establishing a unified description of gluon transverse-momentum-dependent distributions that interpolates between moderate- and small-x regimes while reproducing known Color Glass Condensate results in the high-energy limit.
This paper presents a perturbative framework within chiral effective field theory that solves a hierarchy of integral equations to calculate nucleon-deuteron elastic scattering observables up to next-to-leading order, offering a renormalization-group invariant alternative to direct distorted-wave evaluations.
This paper presents a semi-microscopic four-body continuum-discretized coupled-channels (CDCC) model using the JLM effective interaction that successfully describes neutron and proton elastic scattering off Li, along with relevant cross sections, across the 7 to 50 MeV energy range.
This paper computes charm and strange meson fragmentation functions by deriving and solving a set of twenty-five coupled jet equations based on Poincaré covariant Bethe-Salpeter wave functions, thereby providing a consistent description of quark hadronization across both light and heavy sectors.
This paper proposes parameter-free combinations of particle and anti-particle yields to test thermal models and extract freeze-out chemical potentials () from RHIC BES data, successfully validating these methods against known results while extending predictions to unmeasured (anti-)nuclei yields and providing updated parametrizations for the energy dependence of freeze-out parameters.
This paper investigates how the -cut stiffening scheme applied to the UCIa equation of state affects the equilibrium properties and radial oscillation frequencies of nonrotating neutron stars, demonstrating that the modified model supports stable configurations up to while systematically increasing mode frequencies, thereby validating radial spectra as a complementary probe of high-density nuclear matter.
This paper formulates a complex-valued induced potential between two heavy impurities in a finite-temperature ultracold atomic medium, demonstrating that its universal long-range imaginary component () causes decoherence in both normal fermionic and superfluid phases, and proposes three experimental methods to observe this effect.
This paper establishes a covariant framework for semi-classical spin hydrodynamics in flat and curved spacetimes, demonstrating that spin and fluid modes decouple in the linear regime with damping governed solely by spin relaxation coefficients, while also highlighting the limitations of the Gibbs stability criterion due to equilibrium anisotropy and confirming similar relaxation dynamics in a conformal Bjorken flow background.
