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 investigates the intermittency and fractal behavior of charged particles in Pb-Pb collisions at 5.02 TeV using EPOS4 and PYTHIA8 simulations to analyze large density fluctuations as potential signatures of the QCD phase transition and critical point.
This paper utilizes the String Melting mode of the AMPT model to investigate the scaling behavior and intermittency of charged particle multiplicity fluctuations in Xe–Xe collisions at = 5.44 TeV, determining key parameters such as anomalous fractal dimensions and scaling exponents to characterize the system's self-similar dynamics and provide baseline predictions.
This paper employs a two-flavor Nambu--Jona-Lasinio model coupled with a light-cone quark model to calculate and analyze the in-medium valence quark distribution, electromagnetic form factor, and distribution amplitude of the pion at finite baryon density, comparing the resulting parton distribution functions and their Mellin moments with experimental data, lattice QCD, and theoretical predictions after NLO DGLAP evolution.
Using the interacting boson model with configuration mixing, this study identifies the even-even Sr isotopes as a region of intertwined quantum phase transitions where a crossing between normal and intruder configurations coincides with a shape evolution within the intruder configuration, a scenario strongly supported by comprehensive comparisons with experimental data.
This paper investigates fundamental quasiradial oscillations in slow-rotating pure and hybrid neutron stars using various equations of state and Gibbs construction, highlighting characteristic differences in their oscillation frequencies during spin-down.
This paper identifies the Coulomb bridge mechanism as the dominant driver of peripheral polarization in weakly bound halo projectiles, demonstrating through a decomposed Feshbach dynamical polarization potential that Coulomb-mediated P-Q couplings are essential for breakup-induced absorption in high-angular-momentum reactions.
This paper proposes a novel inverse problem framework for calculating non-perturbative QCD quantities by deriving them from high-energy perturbative inputs, utilizing Tikhonov regularization to stabilize the inherently ill-posed problem and demonstrating its efficacy through toy models.
Using leading-order Faddeev techniques in the zero-coupling limit, this study demonstrates that the system exhibits universal Efimovian halo-bound characteristics, where ground state properties are rendered regulator-independent through the inclusion of a three-body force.
This paper quantifies the theoretical uncertainty of the neutrinoless double-beta decay nuclear matrix element for Ge by applying a rigorous statistical protocol with bounded fluctuations to effective interactions and Bayesian Model Averaging, yielding a central value of 2.46 with a standard deviation of 0.25.
This paper employs bootstrap techniques to demonstrate that both contact-term renormalization and the exact N/D method yield statistically consistent two-nucleon effective field theories, with the NLO potential significantly extending the valid energy range compared to LO when applied to the partial wave.
