Nucl-Ex represents the dynamic frontier where scientists probe the fundamental building blocks of matter through high-energy experiments. By smashing particles together at incredible speeds or observing rare cosmic events, researchers uncover the forces that govern our universe and test the limits of our current understanding of physics.
At Gist.Science, we ensure these breakthroughs reach a broader audience by processing every new preprint in this field directly from arXiv. For each study, we provide both a clear, plain-language explanation of the core discoveries and a detailed technical summary for those seeking deeper insights. Below are the latest papers in nuclear experiment research, curated to help you stay informed on the latest developments from the lab.
This review outlines modern strategies utilizing dispersion relations, lattice gauge theory, and nuclear many-body calculations to reduce hadronic and nuclear uncertainties in radiative corrections for low-energy weak interaction processes, thereby enhancing the precision of searches for physics beyond the Standard Model.
This paper derives a Wandzura-Wilczek-like relation and a Burkhardt-Cottingham-like sum rule connecting the twist-2 and twist-3 tensor-polarized partonic structures of the spin-1 deuteron, and uses HERMES data to phenomenologically estimate that the twist-3 distribution is comparable in magnitude and shape to the twist-2 distribution , suggesting significant subleading-twist effects for future low- experiments.
This paper introduces PDG2021+, an updated and transport-ready hadron list based on the 2021 Particle Data Booklet for heavy-ion collision simulations, and validates its impact on key observables like the pion mean transverse momentum while quantifying systematic uncertainties arising from decay modeling approximations.
This paper introduces a qubit-qutrit quantum tomography technique to certify entanglement in and systems despite incomplete density matrix data, thereby providing a novel probe of nonperturbative QCD hadronization and spin evolution.
This paper demonstrates that incorporating physics-based theoretical structures into the mean functions and kernels of Gaussian Process Regression significantly enhances interpolation accuracy, uncertainty calibration, and extrapolation reliability for nuclear physics problems compared to agnostic baselines.
Using Bayesian inference on multimessenger data and a physics-agnostic equation of state, this study favors a "two-family" scenario where neutron stars and strange quark stars coexist, identifying PSR J0740+6620 as a quark star and providing astrophysical support for the absolute stability of strange quark matter.
This paper demonstrates that the CRYO ASIC, a cryogenic application-specific integrated circuit designed for direct operation in liquid xenon, meets the nEXO experiment's charge readout requirements by achieving high gain stability, reliable in-situ calibration, and low noise performance while mitigating boiling effects through elevated pressure operation.
Using the conventional spherical shell model and the new triaxial projected shell model, this study calculates M1 and E2 gamma strength functions across various isotopes to reveal that deformation-induced splitting and fragmentation of single-particle multiplets generate a bimodal low-energy magnetic radiation structure comprising the scissors resonance and the LEMAR spike.
This paper presents a systematic study of extended sets of E2 matrix elements for various nuclides using the Triaxial Projected Shell Model, successfully accounting for experimental energies and both intra- and inter-band transition properties.
This paper demonstrates that transverse momentum conservation is the dominant mechanism causing the breakdown of azimuthal correlation factorization in small systems, quantitatively explaining CMS p-Pb data and establishing a sign rule where deviations from unity alternate based on harmonic order, thereby necessitating the subtraction of this kinematic effect to isolate genuine flow fluctuations.
