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.

Investigating Roles of Triple Excitations for High-precision Determination of Clock Properties of Alkaline Earth Metal Singly Charged Ions

This study employs relativistic coupled-cluster theory to demonstrate the critical importance of triple excitations in accurately determining the electric dipole polarizabilities and quadrupole moments of clock states in singly charged alkaline-earth metal ions (Ca+^+, Sr+^+, and Ba+^+), while also deriving nuclear quadrupole moments that reveal significant deviations from existing literature values.

ToMCCA-3: A realistic 3-body coalescence model

This paper introduces ToMCCA-3, a realistic three-body coalescence model based on the Wigner function formalism and constrained by modern nuclear interaction data, which successfully predicts light (anti)nuclei yields in proton-proton collisions at 13 TeV and demonstrates their sensitivity to nuclear wave functions when compared with ALICE experimental data.

Convergence in charmonium structure: light-front wave functions from basis light-front quantization and Dyson-Schwinger equations

This paper demonstrates a remarkable convergence between Basis Light-Front Quantization and Dyson-Schwinger equations in predicting charmonium light-front wave functions and associated observables, thereby validating both Hamiltonian and Lagrangian approaches for studying non-perturbative QCD structure.

Accessing baryon-antibaryon generalized distribution amplitudes in e±γ→e±BBˉe^{\pm} γ\to e^{\pm} B \bar{B}

This paper investigates the feasibility of extracting baryon-antibaryon generalized distribution amplitudes from the e±γ→e±BBˉe^\pm \gamma \to e^\pm B \bar{B} process using QCD factorization and numerical estimates, demonstrating that such a measurement is achievable at the Belle II experiment.

Three-body resonances of ααMααM clusters (M=ϕM=ϕ, J/ψJ/ψ, ηcη_c) in M8Be^{8}_{M}{\mathrm{Be}} nuclei

This study investigates the structural effects of ϕ\phi, J/ψJ/\psi, and ηc\eta_c mesons on 8^8Be nuclei using HAL QCD potentials and the Gaussian expansion method, revealing that the ϕ\phi meson strongly binds the system into stable states while J/ψJ/\psi and ηc\eta_c interactions are weaker and form only shallow bound states, with specific predictions for new α\alpha-charmonium bound states and the non-Borromean nature of J/ψ8Be^{8}_{J/\psi}\text{Be}.
