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 review traces the evolution of understanding s-process nucleosynthesis in low-mass AGB stars from early nuclear systematics to modern stellar modeling, highlighting how observational constraints necessitated a shift from the high-temperature Ne(,n)Mg neutron source to the low-temperature C(,n)O reaction as the primary mechanism for synthesizing elements between Sr and Pb.
This study demonstrates that E0 transition strengths and their ratios serve as powerful constraints for narrowing the parameter space of the Interacting Boson Model, a methodology validated through its application to even-even Xe isotopes.
This paper demonstrates how to extract baryon light-front wave functions from equal-time lattice QCD correlators by proving their factorization into a three-quark color-singlet component, a residual lattice factor, and a soft factor, while also verifying the wave function's renormalizability and deriving its evolution equations.
Using fully microscopic time-dependent Hartree-Fock simulations, this study reveals that the quasifission dynamics in the reaction are governed by a complex interplay between collision geometry and incident energy, where specific energy windows can suppress shell effects to potentially enhance the fusion probability for synthesizing superheavy element 119.
This paper calculates enhanced electroweak, QCD, and QED radiative corrections to the nucleon coupling constants and , providing updated relations between lattice-QCD and physical values that yield a total correction of approximately 3.5% to 5.6% and predict a physical axial charge of 1.265(26) or 1.240(9) depending on the input methodology.
This study utilizes an extended Integrated HydroKinetic Model to analyze light-hadron production in Au+Au collisions at RHIC Beam-Energy-Scan energies, demonstrating that both crossover and first-order phase transition equations of state can similarly describe soft particle spectra when parameters are adjusted, with the most significant distinctions appearing in proton and kaon yields at the lowest energy of 7.7 GeV.
This paper extends the macroscopic effective-surface model of neutron stars to rotating systems by deriving analytical expressions for angular momentum and adiabatic moments of inertia within General Relativity, revealing that strong gravity and surface correlations significantly constrain the accessible neutron star radii.
This paper develops an analytic field-theoretic approach to interacting two-body tunneling by deriving the Bethe-Salpeter equation for a Yukawa-coupled tunneling field, demonstrating a closed-form solution in the 1+1 dimensional instantaneous positive-energy regime, and confirming physical consistency through the recovery of the Lippmann-Schwinger equation.
This study employs a macroscopic-microscopic statistical framework to investigate how thermal shell quenching at high temperatures drives shape coexistence and structural changes in Mo and Ru isotopes, thereby significantly influencing their decay modes and lifetimes within the astrophysically relevant r-process path around mass number A = 100.
This paper investigates the feasibility of extracting infinite-volume scattering phase shifts on quantum computers using a one-dimensional trapped system model, demonstrating that while the method yields accurate results with two qubits on IBM hardware, it currently fails with three qubits due to gate operation and thermal relaxation errors.
