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.

Accelerator neutrinos as a probe of in-medium hyperon potentials

This paper proposes that accelerator neutrino experiments, specifically SBND and DUNE, can serve as terrestrial probes for in-medium hyperon potentials by analyzing charged-current interactions that produce $\Lambda$ and $\Sigma$ hyperons inside nuclei, with the StrangeMC simulation forecasting a precision of approximately 6 MeV for the $\Lambda$ potential ( $U_\Lambda$ ) and highlighting the role of hyperon-nucleon cross sections in constraining the $\Sigma$ potential ( $U_\Sigma$ ).

Neutrino-induced hyperon final-state interactions as constraints on the in-medium hyperon potential

This paper demonstrates that charged-current neutrino interactions on argon at facilities like DUNE and SBND can constrain in-medium hyperon potentials through final-state interaction observables, thereby providing critical inputs to resolve the hyperon puzzle in neutron star equations of state.

In-medium hyperon potentials and the quarkyonic hyperon onset: charged $\Sigma$ 's in $\beta$ -equilibrium and the neutrino connection

This paper demonstrates that quarkyonic matter, when dressed with in-medium hyperon potentials constrained by hypernuclear and neutrino data, statistically resolves the neutron-star hyperon puzzle by delaying the onset of charged $\Sigma$ hyperons and suppressing core strangeness, thereby allowing for hyperon-free $2\,M_\odot$ stars while predicting a significantly reduced sensitivity of the maximum mass to hyperon potentials compared to mean-field models.

Running coupling effects in the anti-collinear resummation in high energy evolution

This paper investigates how the running of the QCD coupling affects anti-collinear resummation in JIMWLK evolution, deriving a resummed BFKL kernel that reveals a significant reduction in the Pomeron intercept due to combined resummation and coupling effects, despite a surprising cancellation that leaves the characteristic function at $\gamma=1$ unchanged.

Maris polarization in the ($p,pd$) reaction

This paper theoretically demonstrates that Maris polarization, an effective polarization arising from nuclear absorption and spin-orbit coupling, can be observed in the proton-induced deuteron knockout (p,pd) reaction at 250 MeV through the vector analyzing power $A_y$ , thereby offering a method to determine the total angular momentum $j$ of deuteron-cluster orbits.

Factorization of elastic, single, and double diffractive $pp$ scattering

Using effective field theory, this paper factorizes elastic, single, and double diffractive $pp$ scattering in the Regge limit to demonstrate that while rapidity anomalous dimensions and Pomeron evolution are universal, the diffractive parton distribution functions differ between $ep$ and $pp$ processes, thereby establishing their non-universality in hadronic collisions.

Neutral pion momentum in hypertriton mesonic decay through a root-finding method

This paper validates a Newton-Raphson root-finding method for calculating pion momenta in hypertriton mesonic decays by confirming its accuracy against known negative-pion decay data and subsequently predicting the neutral-pion momentum ($118.129 $MeV/$ c$) for the experimentally inaccessible channel, thereby establishing the approach as a robust tool for future studies of complex multi-body decays.

Ghosts Hunting in the Yang-Mills Vacuum

This paper analyzes zero-modes in a one-loop semi-classical Yang-Mills theory in 3+1 dimensions, demonstrating that they arise from gauge redundancy and, through proper gauge fixing with a bosonic ghost term and zeta-function regularization, yields a finite effective theory that reproduces the known one-loop beta-function.

Nuclear Many-Body Systems as Benchmarks for Quantum Computing

This paper introduces a framework and the NuQuLib software stack for benchmarking quantum algorithms on realistic nuclear many-body systems by mapping chiral effective field theory Hamiltonians to qubit representations and comparing the resource requirements of eigenvalue algorithms like Quantum Phase Estimation, Quantum Krylov methods, and Observable Dynamic Mode Decomposition.
