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.
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.
This paper demonstrates that longitudinally polarized protons can induce chirality in the final states of intermediate-energy reactions involving non-coplanar momenta, a phenomenon quantified by the analyzing power and explained through the coupling of incident proton helicity to the orbital chirality of single-particle wave functions.
The GlueX experiment at Jefferson Lab reports the first observations of and photoproduction alongside production, revealing forward-peaked angular distributions consistent with Regge-like -channel exchanges and a phenomenological double-exchange model, while finding no narrow resonant structures and observing a suppression of pairs similar to other reactions.
This paper demonstrates that the mass spectra of both mesons and baryons are accurately described by a parameter-free open-string model with a consistent Hagedorn temperature of approximately 0.34 GeV, supporting the view of baryons as quark-diquark systems and offering new insights into quark deconfinement.
This paper demonstrates that charm quarks produced in the early pre-equilibrium glasma stage of high-energy proton-nucleus collisions acquire significant elliptic flow () through interactions with non-Abelian fields, suggesting that pre-hydrodynamic dynamics play a crucial role in the observed heavy-flavor collectivity in small systems.
