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.

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 recent ALICE measurements from July 2025 LHC runs involving proton-oxygen, oxygen-oxygen, and neon-neon collisions, detailing charged-particle pseudorapidity densities, flow coefficients, and neutral pion suppression to advance the understanding of particle production and collective phenomena in small collision systems.
This paper calculates next-to-leading order nuclear matrix elements for two-neutrino double-beta decay to excited states in key isotopes using the nuclear shell model, finding that while NLO corrections are typically small, they can become significant due to leading-order cancellations, and that nuclear deformation and seniority structure critically influence the predicted half-lives.
This paper presents flexible, single-photon sensitive optoelectronic fibres integrated with silicon photomultipliers and tungsten-merino wool braiding, enabling the machine-weaving of large-area, conformal textile fabrics capable of real-time, high-spatial-resolution gamma radiation dosimetry.
This study demonstrates that in high-energy oxygen-oxygen collisions at 5.36 TeV, the produced QCD matter only partially reaches local equilibrium, necessitating a core-corona framework rather than a purely hydrodynamic approach to accurately describe the dynamics, particularly the incomplete chemical equilibrium observed in strange baryon yields.
This study demonstrates that using transverse spherocity to classify Pb+Pb collisions into isotropic and jetty topologies provides a cleaner and more reliable method for probing the Chiral Magnetic Effect by effectively suppressing flow-driven and resonance-decay backgrounds compared to traditional flow-vector-based approaches.
The CMS experiment at the LHC reports the first observation of nuclear suppression in coherent (1S) photoproduction off heavy nuclei, measuring a nuclear gluon suppression factor of at a high energy scale of GeV and .
This paper presents a comprehensive prediction of particle-induced backgrounds for the NUCLEUS experiment at the Chooz nuclear power plant, demonstrating through environmental measurements and Geant4 simulations that the setup achieves sufficient background rejection to enable the detection of Coherent Elastic Neutrino-Nucleus Scattering with a signal-to-background ratio greater than one in the sub-keV energy range.
This paper demonstrates that while GS20 is a proven portable neutron detector, CLYC detectors are superior for neutron resonance transmission analysis in high gamma-radiation environments typical of thorium-based safeguards due to their strong pulse-shape discrimination capabilities, which yield significantly more precise measurements despite longer decay times.
This paper introduces HISP, an open-source simulation tool used to demonstrate that baking is the most effective method for removing tritium from ITER's plasma-facing components, significantly outperforming Glow Discharge Conditioning and low-power deuterium pulses which had minimal impact on the final inventory.
Using the MIMAC-35 cm detector, researchers successfully measured and identified 51 thermal neutron capture events in hydrogen by discriminating 1.3 keV deuteron tracks from a background of over 11 million events, demonstrating the detector's capability to search for low-energy rare events without shielding.
