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.

D-meson production via sequential hadronization in high-energy nuclear collisions

This paper investigates charm-quark hadronization in high-energy nuclear collisions using a sequential coalescence model coupled with Langevin transport, successfully reproducing ALICE's DsD_s and D0D^0 elliptic flow data and predicting a low-pTp_T peak in the Ds/D0D_s/D^0 yield ratio driven by strangeness enhancement.

Electric charge fluctuations from lattice QCD in the continuum limit

Using a 4HEX action to achieve the continuum limit, this study presents the first lattice QCD calculation of fourth-order electric charge fluctuations, revealing a persistent tension with the hadron resonance gas model that is only partially mitigated by including light meson interactions and suggesting a future LHC measurement of the χ4Q/χ2Q\chi_4^Q/\chi_2^Q ratio to resolve the discrepancy.

Constraining the Low-pTp_T η/π0\eta/\pi^0 Ratio for Direct-Photon Analyses with Blast-Wave Fits to π\pi, KK, and pp Spectra

This paper proposes a data-constrained method using blast-wave fits to charged hadron spectra to predict the low-pTp_T η/π0\eta/\pi^0 ratio, thereby significantly reducing background uncertainties for direct-photon and dilepton measurements in heavy-ion collisions.

Analytic structure of the QCD phase diagram in the complex-temperature plane

This paper investigates the analytic structure of the QCD phase diagram by treating temperature as a complex variable, combining universal critical scaling, effective models, and lattice-QCD data to locate the nearest Yang-Lee edge singularities and establish a consistency test for critical-point searches via the relationship between complex-temperature and complex-chemical-potential trajectories.
