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.

Shedding light on the nature of ϕ(2170)\phi(2170) with the parton and hadron cascade model PACIAE

Using the PACIAE 4.0 model to simulate e+e−e^+e^- collisions at s=4.95\sqrt{s}=4.95 GeV, this study evaluates various structural interpretations of the ϕ(2170)\phi(2170) resonance—including strangeonium, hybrid, tetraquark, and molecular configurations—by calculating their production yields and identifying distinct rapidity and transverse momentum spectral signatures that can distinguish their true nature.

ΛΛˉ\Lambda \bar \Lambda spin correlations in high-energy collisions from quantum channels: an open quantum system view of hadronization

This paper proposes an open quantum system framework using quantum channels to model ΛΛˉ\Lambda \bar \Lambda spin correlations during hadronization, demonstrating that experimental data aligns with a two-qubit depolarizing channel and offering new insights into confinement dynamics beyond simple entanglement classification.

Extraction of the nucleon axial form factor from Lattice QCD using NNLO chiral perturbation theory

This paper presents a model-independent extraction of the nucleon axial form factor by fitting NNLO chiral perturbation theory with explicit Δ(1232)\Delta(1232) resonance contributions to lattice QCD data, successfully describing pion-mass and momentum dependencies to yield precise physical-point values for the axial charge and radius.

FRG analysis of dense two-color QCD within the linear sigma model

This paper employs the functional renormalization group method within a linear sigma model to investigate the phase structure and U(1)AU(1)_A anomaly effects in dense two-color QCD, revealing that while anomaly couplings for mesons are enhanced by the quark chemical potential, the topological susceptibility is suppressed at high densities and chiral partners exhibit mass degeneracy upon chiral restoration.

Cooling of Hybrid Stars with a 2SC+$$ Phase

This paper presents the first study of the thermal evolution of hybrid stars containing a newly proposed 2SC+$$ phase, finding that the inherited 3P2{}^3P_2 superfluidity suppresses quark β\beta decay to produce hotter stars than the traditional 2SC phase, a signature potentially detectable through low-temperature observations of specific pulsars.

Strong Evidence for Three-α\alpha Clustering in the Ground State of 12C^{12}\mathrm{C}

By analyzing 12C(p,pα)8Be^{12}\mathrm{C}(p,p\alpha)^{8}\mathrm{Be} data using distorted-wave impulse approximation, this study demonstrates that an unrestricted three-α\alpha cluster model successfully reproduces experimental cross sections while mean-field models fail, providing strong evidence for a pronounced three-α\alpha cluster structure in the ground state of 12C^{12}\mathrm{C}.
