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 reports the first measurement of the state lifetime in Sn using thermal-neutron capture, where the observed enhanced transition strength provides compelling evidence for multiple shape coexistence, a finding corroborated by theoretical calculations predicting three distinct nuclear shapes in the Sn isotopes.
This paper outlines a proposed physics program using the upgraded CLAS12 detector to explore the three-dimensional quark and gluon structure of the nucleon through precision measurements of Double Deeply Virtual Compton Scattering, Timelike Compton Scattering, and near-threshold production via di-muon electro- and photoproduction.
This paper proposes an augmentation method utilizing momentum conservation in -jet events to correct for jet-medium interaction effects in Energy-Energy Correlators (EECs) within heavy-ion collisions, thereby enabling a more precise extraction of jet shower dynamics and providing a novel tool to test QGP energy loss scenarios.
Using high-precision x-ray spectroscopy of muonic chlorine atoms combined with advanced theoretical calculations, researchers determined the charge radii of stable Cl and Cl isotopes with an order-of-magnitude improvement in precision, resolving previous discrepancies in mirror nuclei trends and establishing new reference values for future studies.
The SIDDHARTA-2 collaboration utilized a novel room-temperature CZT detection system at the DANE collider to report the first absolute X-ray yield measurements for kaonic fluorine and new data for kaonic copper, revealing systematic transition dependencies and strong-interaction effects that provide crucial constraints for exotic atom cascade models.
This paper reports the successful design, construction, and beam testing of a pilot 3D-projection detector using opaque water-based liquid scintillator (oWbLS), demonstrating its effective optical confinement and high timing resolution to validate the technology as a scalable concept for future particle physics experiments.
The authors successfully demonstrated a new in-situ Cockcroft-Walton high-voltage generation system integrated into the AXEL xenon gas time projection chamber, which eliminated the need for external high-voltage feedthroughs and achieved an energy resolution of 0.67% at 2615 keV during a 40-day operation at 6.8 bar.
This paper presents the first results from the SWEET project, demonstrating the use of sucrose crystals as a hydrogen-rich phonon detector with scintillation capabilities for probing sub-GeV/c dark matter through elastic nuclear scattering.
This paper reviews the motivation and early experimental results from the July 2025 LHC light-ion run (pO, OO, and NeNe collisions), which provide strong evidence for quark-gluon plasma formation in small systems and bridge the gap between perturbative QCD, hot QCD, and low-energy nuclear structure physics.
This work analyzes experimental data from a 2022 petawatt laser facility to derive an effective single-shot temperature and a non-equilibrium "TNSA equation of state" for quasineutral plasmas and demonstrates that deviations from the ideal gas limit are well described by Korteweg-de Vries soliton solutions.
