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 study introduces a data-driven approach to quantify global vorticity in relativistic heavy-ion collisions by analyzing transverse momentum spectra across various hadron species and collision conditions, revealing significant dependencies on particle type, centrality, and beam energy that offer new insights into the rotational dynamics and freeze-out properties of quark-gluon plasma.
Using CMS data from PbPb collisions at 5.02 TeV, this study measures the azimuthal anisotropy of prompt D mesons and finds their flow coefficients to be consistent with those of D mesons, indicating that the strangeness content does not significantly alter the mesons' interaction with the quark-gluon plasma within the measured transverse momentum range.
Using the CLAS12 detector at Jefferson Lab, researchers reported the first measurement of beam spin asymmetries for dihadrons in semi-inclusive deep inelastic scattering, employing a machine learning-based photon classifier to significantly enhance statistics and revealing a nonzero asymmetry sensitive to the twist-3 quark-gluon correlation PDF as well as the first experimental evidence for the isospin dependence of the helicity-dependent dihadron fragmentation function .
Using delayed-coincidence analysis of the RnPo decay chain detected by a low-background LaBr scintillator, the authors determined the most precise half-life of Po to date as (stat.)(syst.) ms.
This paper employs a consistent folding model with a realistic density-dependent nucleon-nucleon interaction to simultaneously describe both elastic C scattering and the astrophysical factors of the radiative capture C reactions at low energies.
Using the self-consistent Skyrme Hartree-Fock in the continuum method, this study calculates the proton elastic scattering excitation function from Be to successfully reproduce and interpret the narrow near-threshold resonance in B as an single-proton state, thereby supporting recent experimental findings at the NSCL.
This paper employs a spherical Skyrme-force Hartree-Fock BCS quasi-particle random phase approximation to map the landscape of nuclear deformation softness across the nuclide chart, diagnosing ground-state instabilities and calculating multipole polarizability to reveal the interplay between intrinsic nuclear shapes, shell structure, and low-lying collective dynamics.
This study combines time-of-flight measurements of beta-delayed neutron emission from Cd with large-scale shell model calculations to demonstrate that the decay is driven by a specific transition, thereby validating the model's superior predictive accuracy over global models like FRDM for -process waiting points.
This paper presents a comparative simulation study using Geant4 and FLUKA to benchmark and optimize a 30 MeV proton-induced beryllium neutron source, evaluating neutron fluence, gamma dose, and moderation effects to guide the design of a modular irradiation station for thermal neutron fields.
This paper generalizes the Semkow summing correction formalism into matrix and partitioned frameworks to analyze 180-degree and gated coincidence events in the GRIFFIN spectrometer, ultimately demonstrating that the statistical deviations inherent in these corrections bound the sufficient measurability of true coincidence summing.
