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.
This study employs a Poincaré-covariant contact interaction model to derive the equation of state for strange quark stars, demonstrating that specific parameter sets for interaction strength and ultraviolet cutoff yield mass-radius relations and tidal deformabilities consistent with multi-messenger astrophysical observations.
Using the two-flavor Linear Sigma Model with quarks at one-loop order, this study demonstrates that the chiral phase transition at zero temperature and finite baryon density is of first order, occurring when the chemical potential equals the vacuum quark mass, as evidenced by discontinuities in the chiral condensate, particle masses, couplings, and the speed of sound.
This paper solves the Dyson-Schwinger equations for the Landau gauge quark-gluon vertex in quenched QCD to demonstrate that while its transverse form factors exhibit weak angular dependence, this does not constitute planar degeneracy, while simultaneously confirming that dynamical chiral symmetry breaking relies on a mutually generated tensor coupling and that the resulting quark propagator is consistent across different Yang-Mills solutions with poles only on the real time-like axis.
Using the AMPT model, this study demonstrates that while the nonlinear response coefficient grows dynamically during the evolution of relativistic heavy-ion collisions, the ratio of this coefficient between U+U and Au+Au systems remains stable across all stages, effectively isolating intrinsic initial-state geometric correlations to support experimental efforts in extracting high-order nuclear structure.
This paper presents a detailed comparison of the SuSAv2 and RDWIA theoretical models against experimental measurements of charged-current neutrino-induced single-pion production from T2K, MINERvA, and MiniBooNE across a broad energy range, highlighting their respective approaches to modeling nuclear targets and pion production channels.
This paper demonstrates that a minimal chiral nuclear force, constrained only in the sector and utilizing a lattice-inspired absolute-momentum regulator, achieves remarkable cutoff independence and accurately reproduces binding energies up to without requiring complex many-body forces.
This paper analyzes the angular momentum selection rules and identifies four dominant electromagnetic background barriers that constrain spectroscopic searches for gravitomagnetic spin-quadrupole coupling in highly charged ions, ultimately deriving the specific multi-isotope experimental topology required to isolate the gravitational signal and establishing a preliminary laboratory bound on the gyrogravitational ratio.
This paper employs nuclear density functional theory to derive a microscopic description of the interaction between nuclear clusters and superfluid phonons in the neutron-star inner crust, revealing a significantly smaller coupling constant than previous hydrodynamical estimates due to the suppression of phonon amplitude within the clusters.
This paper proposes jet correlation observables to unambiguously distinguish instanton-induced processes from perturbative QCD events in proton-proton collisions at the LHC, utilizing constraints derived from 2+1 flavor QCD calculations to guide future searches at the Electron-Ion Collider.
