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 paper reviews experimental data on electric dipole polarizability in nuclei from Ca to Pb, demonstrating how comparisons with theoretical models constrain neutron skin thickness and indicate a soft symmetry energy equation of state around nuclear saturation density.
This paper discusses the significant impact of Angela Bracco's research on the electric dipole response of nuclei by examining three key areas: the decay width of the giant dipole resonance, the equivalence of photo-absorption and emission, and the nature of the pygmy dipole resonance.
This study presents new total photoabsorption cross sections for several $sd$-shell nuclei derived from small-angle 295 MeV proton scattering, comparing the results with artificial neural network predictions and configuration-interaction shell-model calculations to validate the latter's ability to describe fragmented electric dipole strength for applications in ultrahigh-energy cosmic ray research.
This pedagogical review synthesizes experimental data from relativistic nucleus-nucleus collisions with Lattice QCD predictions to explore the existence and properties of the quark-gluon plasma and the broader QCD phase diagram.
This paper presents a supervised machine learning approach for automating nuclide identification in HPGe gamma spectrometry, which achieves a superior F1 score of 0.97 compared to traditional software (0.84) and utilizes SHAP values to confirm that the model relies on physically relevant photopeaks for its predictions.
This paper employs an effective Lagrangian approach to successfully reproduce the production cross sections of known high-orbital kaon excited states in reactions and predicts that other such states exhibit sizable, forward-peaked cross sections, indicating their strong potential for future experimental observation.
This paper outlines the design and physics capabilities of the Compressed Baryonic Matter (CBM) experiment at FAIR, which aims to explore the QCD phase structure at high net-baryon densities by utilizing a high-rate, triggerless data acquisition system to measure rare probes such as multi-strange hadrons, dileptons, and hypernuclei.
This paper presents a large-scale shell-model investigation of two-neutrino double electron capture in Ba and Kr, providing updated nuclear matrix elements and half-life predictions based on validated effective interactions to support future experimental efforts.
This paper proposes a data-constrained method using blast-wave fits to charged hadron spectra to predict the low- ratio, thereby significantly reducing background uncertainties for direct-photon and dilepton measurements in heavy-ion collisions.
This paper reports high-precision measurements of charged pion multiplicities and their azimuthal modulations in semi-inclusive deep inelastic scattering off proton and deuteron targets using a 10.6 GeV electron beam at Jefferson Lab, revealing consistent transverse momentum dependencies and significant azimuthal asymmetries that will enable improved determinations of quark transverse momentum distributions.
