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 presents Bayesian evidence favoring a continuous, boundary-free crossover between hadronic and quark matter in cold dense environments over conventional first-order or fixed-boundary transitions, revealing a large chiral-invariant nucleon mass and a small quark pairing gap that ensure physical self-consistency across both phases.
This paper demonstrates that QCD thermodynamics in the intermediate-temperature regime can be effectively described by a gas of confining strings with repulsive excluded-volume interactions, where an open-string spectrum characterized by a Hagedorn temperature of approximately 300 MeV and distinct mesonic and baryonic volume parameters successfully reproduces bulk lattice-QCD data above the pseudocritical temperature.
This study investigates the role of dynamical Coulomb effects in explaining the observed splitting between and femtoscopic radii in central Au+Au collisions at few-GeV energies, finding that while baryon-meson interactions and residual-source treatments reproduce key trends, they do not fully account for the experimental data, suggesting a need to further explore charged-source geometry and its interplay with strong interactions.
This paper presents a precise, flexible, and generalizable artificial neural network model trained on experimental data to predict neutron double-differential cross sections in spallation reactions, offering significant benefits for accelerator-driven system design and various nuclear physics applications.
This paper reports the first measurement of the lifetime of the state in Ca using high-resolution in-beam -ray spectroscopy at RIKEN's RIBF, yielding a reduced transition probability that serves as a critical benchmark for shell-model and *ab initio* calculations of neutron-rich calcium isotopes near the shell closure.
This paper investigates the spectroscopic and decay properties of the meson using a nonrelativistic quark model, predicting mass spectra, decay constants, radiative widths, and Regge trajectories while identifying the mass and -wave fine-structure ordering as critical experimental tests for the system's spin-dependent dynamics.
This paper proposes that the simultaneous observation of a nuclear modification factor near unity and significant high- elliptic flow in relativistic Pb collisions is explained by a mechanism where hard partons coalesce with boosted thermal medium partons, resulting in anisotropic collective push that enhances hadron flow while predicting a smaller signal for jets.
This paper proposes and analyzes three cavity QED-enhanced interrogation schemes for solid-state Th nuclear clocks that leverage collective coupling to nanophotonic modes to overcome decoherence limitations and optimize clock frequency instability.
By integrating nuclear structure and isospin-transport experimental data into a Bayesian inference framework for the dense matter equation of state, this study demonstrates that laboratory constraints significantly reduce the probability of the direct Urca cooling mechanism occurring in low-mass neutron stars (below ) to less than 1%.
This paper introduces a controlled sampling scheme to disentangle the effects of tetrahedral one-body density from genuine multi-nucleon correlations in relativistic O + O collisions, demonstrating that specific normalized flow and eccentricity ratios can effectively constrain -cluster compactness and initial-condition model dependence.
