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 study investigates how high external pressure, modeled via an impenetrable spherical cavity, significantly enhances finite-nuclear-size corrections and electron-capture decay rates in confined hydrogenlike ions while lifting level degeneracies and altering the relative magnitudes of these corrections across different bound states.
This paper presents the first unified calculation of twist-3 quark-gluon correlations for both protons and pions using a light-front effective Hamiltonian, demonstrating quantitative consistency with experimental data for Sivers and Boer-Mulders asymmetries.
This study utilizes Total Routhian Surface calculations to explain the distinct signature inversion in the [523]5/2 band and conventional splitting in the [642]5/2 band of Hf by revealing how a Z=72 proton subshell gap locks the core while neutron-driven shape bifurcations and gamma-softness dictate the alignment dynamics and rotational behavior of these signature partner bands.
This paper investigates the Hall viscosity in the quark-gluon plasma generated by non-central heavy-ion collisions, demonstrating that strong magnetic fields or vorticity induce two independent Hall viscosities comparable in magnitude to shear viscosity, which significantly influence hydrodynamic evolution and observable flow 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.
Using the AMPT model, this study demonstrates that femtoscopic source parameters of pion pairs in Pb+Ne and Pb+O collisions at = 68.5 GeV serve as robust signals for detecting unique nuclear structures and initial shape deformations, thereby expanding the scope of nuclear structure investigations to femtoscopic observables.
This paper presents a systematic spurion method that establishes a one-to-one correspondence between low-energy effective theory and chiral Lagrangian operators for weak processes, overcoming the limitations of external source and conventional spurion approaches by avoiding the need for additional spurions when matching higher-dimensional operators relevant to neutrino physics and neutrinoless double beta decay.
This paper demonstrates that a maximum likelihood estimator effectively mitigates non-flow effects and addresses detector acceptance deficiencies in flow analysis, offering a compelling alternative to standard methods like particle correlation and event plane techniques.
