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.

Quantum Computers will constrain the Equation of State of Neutron Stars

This paper outlines a theoretical framework and demonstrates a proof-of-concept simulation using quantum computing to solve the sign problem in Lattice QCD at finite chemical potential, aiming to determine the Equation of State of neutron stars and constrain their static observables in preparation for third-generation gravitational wave detection.

Photon-nucleon entanglement in Compton scattering at low and high energies

This paper investigates spin-spin entanglement in Compton scattering across low and high energy regimes, establishing a no-go theorem for real amplitudes in unpolarized scattering and demonstrating that polarized scattering off nucleons produces diverse maximally entangled states sensitive to electromagnetic polarizabilities, thereby proposing entanglement as a novel probe for nucleon structure.

Three-baryon femtoscopy as an effective 3\rightarrow3 scattering experiment

This paper presents the first measurement of the three-proton correlation function in 13.6 TeV pp collisions at the LHC, demonstrating that three-hadron femtoscopy serves as an effective 3\rightarrow3 scattering experiment that reveals a novel long-range attractive component in the isospin 3/2 three-body system and opens new avenues for studying three-body dynamics in the strangeness sector.

Virial theorem for rigidly rotating matter

This paper employs the virial theorem to derive scaling properties of the thermodynamic free energy for massless fermionic matter in rigid rotation, establishing that hydrodynamic descriptions require a specific hierarchy between the system's size and temperature, and demonstrating that thermodynamic variables depend on angular velocity through the product ΩR\Omega R, a finding consistent with recent lattice QCD simulations and used to estimate the light quark contribution to the moment of inertia in Quark-Gluon Plasma.

Exclusive Quark and Gluon Dijet Production as Probes of GPDs at Collider Energies

This paper investigates exclusive electroproduction of quark and gluon dijets within the collinear factorization framework to probe generalized parton distributions, incorporating helicity contributions and elastic form factors while comparing predictions to HERA data and projecting future measurements for the Electron-Ion Collider.

Quarkoniumlike states above open-flavor thresholds in Born-Oppenheimer EFT

This paper employs Born-Oppenheimer effective field theory to model quarkoniumlike states above open-flavor thresholds, revealing a spectrum organized by heavy-quark spin symmetry that includes both short-distance quarkonium resonances and long-distance molecular states, while providing multiplet assignments for experimental candidates and identifying the need for additional theoretical sectors to explain outliers.
