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 presents the first direct measurement of the F()Ne reaction cross sections using a radioactive F beam at TRIUMF-ISAC, which significantly reduces uncertainties in the reaction rate and reveals a 45% increase in predicted F production for Asymptotic Giant Branch nucleosynthesis models.
This study utilizes the UrQMD transport model to analyze baryon stopping in low-energy Au+Au collisions, revealing that a significant fraction of mid-rapidity protons originate from initial neutrons via isospin conversion, a process that deviates from chemical equilibrium assumptions below 10 GeV and is coupled with the onset of nuclear transparency.
This study independently validates the octupole collectivity and confirms a strongly quenched intrinsic electric-dipole moment in Ra by precisely measuring the lifetimes of its low-lying negative-parity states via -decay, thereby providing a critical benchmark for nuclear models used in searches for electric dipole moments.
This paper reports the first proof-of-principle demonstration of precision -delayed charged-particle spectroscopy at FRIB using , successfully reconstructing its decay scheme, assigning spins and parities to excited states in via spectral interference patterns, and comparing the extracted -strength distribution with shell-model calculations.
This paper applies transfer learning to fine-tune deep neural networks pretrained on carbon-12 data, successfully constructing robust, data-driven models for inclusive electron-nucleus cross sections across various nuclei that outperform existing phenomenological models while systematically analyzing the impact of fine-tuning depth, data availability, and kinematic coverage.
This paper summarizes recent results from the NA61/SHINE experiment at CERN, covering strong interaction studies in various collision systems including rapidity spectra, yield dependencies, transverse polarization, and evidence of isospin symmetry violation in kaon production.
The paper introduces G4VR, a virtual reality extension for the Geant4 toolkit that utilizes a new visualization driver (G4XR) to enable immersive, interactive 3D exploration of particle interactions, tracks, and event chronologies through headsets and hand controllers.
This paper presents three predictions for partonic energy loss in ultrarelativistic light ion collisions by combining BDMPS-Z, weighted path, and JEWEL models with realistic O and Ne geometries to demonstrate how ion size characteristically influences energy loss in small quark-gluon plasma systems.
This review summarizes two decades of heavy-flavor and quarkonium measurements by the PHENIX and STAR experiments at RHIC to elucidate the microscopic structure and transport properties of the quark-gluon plasma, while outlining future prospects enabled by sPHENIX and the Electron-Ion Collider.
Using CMS data from 5.36 TeV PbPb collisions, this study reports the first observation of a significant negative spin-dependent azimuthal asymmetry in coherently photoproduced J/ mesons, confirming a theoretical model where the meson inherits the incident photon's linear polarization and suggesting a novel method for reaction plane determination.
