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 demonstrates that in coupled-channel dynamics, the conventional method of assessing a channel's importance by deleting it is misleading because it conflates intrinsic contributions with model-space reorganization, whereas a basis-preserving decoupling approach reveals that the true contribution is better tracked by the dynamic polarization potential and often exhibits quantum anti-synergy.
This study measures the dipole response of the neutron-rich nucleus He, revealing that its low-energy dipole strength is dominated by two-neutron emission rather than four-neutron decay, and provides experimental values for total dipole strength and polarizability that are compared with state-of-the-art theoretical models.
Using a Monte Carlo event generator with -factorization, the study demonstrates that the observed stronger-than-linear growth of D-meson yields in high-multiplicity pp and pPb collisions is reproduced by various initial-state spatial distributions, indicating that this observable is insufficient for distinguishing the specific matter geometry within the proton.
This paper presents a deterministic quantum algorithm that efficiently constructs antisymmetric fermionic states in first quantization mapping using -gates and dirty ancilla qubits, offering a significant performance advantage over sorting-based methods for systems where the particle count is less than the square root of the available orbitals.
Using chiral perturbation theory, this study derives the one-pion exchange potential in strong magnetic fields, revealing that the potential's range decreases in all directions and induces a deuteron energy shift comparable to its binding energy at field strengths around the pion-mass scale.
This paper investigates whether three anomalous compact objects can be modeled as dark matter admixed neutron stars using a first-principles baryonic equation of state, finding that HESS J1731-347 and PSR J1231-1411 are consistent with small fermionic dark matter fractions while XTE J1814-338 is ruled out as a candidate and instead suggests a twin star scenario.
This paper calculates electroweak radiative corrections to parity-violating electron-nucleus scattering, finding that large cancellations between vertex corrections leave vacuum polarization as the dominant effect, which is negligible for PREX, MREX, and CREX experiments on heavy nuclei but essential for precision measurements on C.
This paper presents an algebraic solution to the self-consistent Nilsson cranking model for the 20Ne nucleus, which yields ground-state rotational-band energies in significantly better agreement with experimental data than previous numerical methods and offers insights into rotation type transitions and weak pairing correlations.
This paper employs potential scattering theory with a parity-dependent surface potential to model the +Be fusion process in the Hoyle resonance region, revealing a double-hump potential structure that predicts unobserved resonances and provides an estimated astrophysical S-factor for practical applications.
By extending the IdylliQ model of Quarkyonic matter to include strangeness, this study demonstrates that -quark saturation delays the onset of hyperons to higher densities (--) and suppresses their occupation, thereby mitigating the hyperon puzzle and preserving the stiffness of neutron star equations of state.
