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.
Using nuclear lattice effective field theory with large volumes and high-precision interactions, this study finds no evidence for a tetraneutron resonance, instead revealing a repulsive-to-weakly-attractive dineutron-dineutron interaction that produces a confined energy state near experimental observations but lacks the characteristic plateau of a resonance.
This paper demonstrates for the first time that neural simulation-based inference (NSBI) can effectively constrain proton parton distribution functions using high-dimensional, unbinned LHC data, achieving significantly improved precision over traditional binned analyses by fully exploiting statistical power and reducing reliance on coarse uncertainty approximations.
This paper presents a quantum-computing framework for three-dimensional nuclear lattice models using a variational quantum eigensolver with Gray code encoding and symmetry reduction, successfully demonstrating accurate ground-state energy calculations for light nuclei (, , and ) that converge toward experimental values as lattice size increases.
This paper reviews the formalism of response theory for isolated quantum fields with unitary time evolution, emphasizing the consequences of causality, time-reversal symmetry, and conservation laws on spectral representations, generating functionals, fluctuation-dissipation relations, and the statistics of work.
This study utilizes a second-order relativistic viscous hydrodynamic framework to quantify the contributions of thermal vorticity and evolving magnetic fields to the global spin polarization of hyperons, finding qualitative agreement with recent ALICE measurements at TeV energies and offering new insights into the vortical structure of QCD matter.
This paper proposes that neutron-nucleus interactions with anomalously large scattering lengths could enable the observation of the Efimov effect in nuclear systems, specifically investigating the potential for B to exist as a B-- Efimov trimer.
This study utilizes the AT-TPC within the SOLARIS solenoid to perform the first high-luminosity inverse kinematics Be() transfer reaction measurement, determining spectroscopic factors for Be states up to 3.40 MeV and providing evidence through comparison with NCCI calculations that the 3.40 MeV state has positive parity, consistent with it being the second excited state of the ground-state rotational band.
This paper introduces a novel, manifestly covariant relativistic formalism that derives deterministic equations for the evolution of non-Gaussian fluctuations and three-point correlations in stochastic hydrodynamics, successfully addressing the complex problem of correlating fluctuating velocity within a unified multi-component matrix framework.
This paper presents a global Bayesian analysis of unpolarized quark transverse-momentum-dependent parton distribution functions using Drell-Yan data at and accuracy, leveraging AI-driven functional form selection and machine-learning emulators to enable efficient Markov Chain Monte Carlo sampling and quantify uncertainties.
This paper investigates the effects of rotation on QCD phase transitions using a Polyakov-enhanced linear sigma model, revealing that while the model successfully describes mechanical properties and satisfies the Tolman-Ehrenfest law in the large-volume limit, it predicts a decrease in critical temperatures with increasing rotation that contradicts first-principle lattice results.
