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.

Below are the latest papers in nuclear theory, distilled and ready for you to explore.
This paper presents a method using multilayer perceptron neural network emulators to rapidly solve Tolman-Oppenheimer-Volkoff equations within the PyCBC framework, enabling the direct inference of nuclear equation-of-state parameters from gravitational-wave data with a nearly two-orders-of-magnitude speedup and negligible loss of accuracy compared to traditional solvers.
This study demonstrates that incorporating QCD small- energy evolution (JIMWLK) into the IP-Glasma initial state framework significantly alters key heavy-ion collision observables, such as particle multiplicities and flow correlations, highlighting the critical necessity of nonlinear QCD evolution for accurately modeling early-stage dynamics and extracting quark-gluon plasma transport properties.
This paper reports on the spectroscopy of neutron-rich 51Ca via the 50Ca(d,p) reaction, identifying single-particle states and a candidate 9/2+ excitation to provide new constraints on shell evolution in calcium isotopes through comparison with shell-model and ab initio VS-IMSRG calculations.
This study calculates the primordial deuterium abundance using a consistent potential-model approach for and reactions based on the Malfliet-Tjon interaction, yielding a ratio of that aligns well with observational data from metal-poor damped Lyman- systems.
This study demonstrates that total reaction and elastic scattering cross sections serve as effective probes for identifying the spin-parity and particle-hole configurations of nuclei in the island of inversion by correlating them with specific nuclear density profiles predicted via antisymmetrized molecular dynamics and the Glauber model.
This paper establishes a non-perturbative Green's function formalism that models sub-barrier proton-nucleus scattering via a surface delta-shell impurity, successfully predicting resonance energies for , , and systems while distinguishing between weak-coupling threshold states and saturated geometric plateau states.
This paper introduces a new parametrization for N-point energy correlators that enables the derivation of a general factorization theorem in the back-to-back limit and the analytic determination of leading non-perturbative power corrections for arbitrary N, including non-integer values, thereby facilitating future precision extractions of the strong coupling constant.
This study resolves a long-standing discrepancy in the to transition strength of Fe by using Coulomb-excitation measurements to demonstrate that previous lifetime data were overestimated due to outdated electronic stopping power models, thereby confirming the validity of shell-model predictions.
This paper formulates a relativistic hydrodynamic theory for fluids with spin and intrinsic dilation charges, deriving constitutive relations that reveal gapped dilation excitations and scale-anomaly-induced transport effects, which reduce to microstretch fluid dynamics in the nonrelativistic limit and apply to rapidly expanding or contracting nearly conformal systems.
This paper investigates the late-time asymptotic behavior of superfluid Bjorken flow using Mueller-Israel-Stewart theory coupled to a complex scalar field, revealing that dissipative evolution leads to novel transseries solutions containing factors that encode initial data dilution and exhibit either damped fall-off or oscillations depending on the condensate relaxation rate, with potential implications for heavy-ion collision experiments.
