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.

Scattering of a weakly bound dimer from a hard wall in one dimension

This paper investigates the one-dimensional scattering of a weakly bound dimer from a hard wall by computing phase shifts and reflection coefficients across various energies and mass ratios, while analytically deriving low-energy consistency with prior work, logarithmic mass-ratio dependencies via the Born-Oppenheimer approximation, and high-energy dissociation probabilities and angular distributions.

A compendium of cold-nuclear matter baseline predictions in light-ion collisions

This paper presents comprehensive perturbative QCD baseline predictions for cold nuclear matter effects in light-ion collisions at LHC energies, demonstrating that while these effects induce significant suppressions with large uncertainties, specific multi-cross-section ratios can effectively cancel these uncertainties to enhance the sensitivity to quark-gluon plasma signatures.

Comparison of Pauli projection and supersymetric transformation methods for three-body nuclear structure and reactions

This paper compares two methods for eliminating Pauli-forbidden states in three-body nuclear systems—Pauli projection and supersymmetric transformation—finding that while Pauli projection better matches experimental deuteron-4{}^4He scattering data, neither method demonstrates clear superiority for bound and resonant states, though systematic differences between them are observed.

Resolving the structure of bound states using lattice quantum field theories

This paper presents the first lattice calculation of a two-to-two particle matrix element using pionless effective field theory to demonstrate that while finite-volume formalism is unnecessary for deep-bound states, it is critical for accurately determining the infinite-volume elastic form factors and charge radii of shallow-bound states like the deuteron.

Emergent Gribov horizon from replica symmetry breaking in Yang--Mills theories

This paper demonstrates that the Serreau–Tissier replica sector in Yang–Mills theories can dynamically generate a Gribov–Zwanziger-type horizon functional through the expansion of the Faddeev–Popov determinant, thereby providing a microscopic mechanism for the emergence of the Gribov scale that yields either a Curci–Ferrari mass or a refined Gribov–Zwanziger decoupling propagator depending on the replica symmetry phase.
