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.

Single-Photon Sensitive Optoelectronic Fibres for Distributed Nuclear Radiation Detection in Textile Fabrics

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.

Observation of nuclear suppression in coherent Υ\Upsilon(1S) photoproduction off heavy nuclei at the LHC

The CMS experiment at the LHC reports the first observation of nuclear suppression in coherent Υ\Upsilon(1S) photoproduction off heavy nuclei, measuring a nuclear gluon suppression factor of RgPb0.55R_\text{g}^\text{Pb} \approx 0.55 at a high energy scale of μ2=22.4\mu^2 = 22.4 GeV2^2 and x103x \approx 10^{-3}.

Particle background characterization and prediction for the NUCLEUS reactor CEννNS experiment

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.

Characterization of GS20 and CLYC Detectors for Neutron Resonance Transmission Analysis in High Radiation Environments

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.

3D-Deuteron Track Recoils Produced by Neutron Capture in Hydrogen Measured by MIMAC-35 cm

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.

Measure charge transport in high-energy nuclear collisions with an energy scan of isobaric collisions

This paper proposes a beam-energy scan of isobaric collisions (Ru+Ru vs. Zr+Zr) to precisely measure electric-charge transport and distinguish between competing microscopic mechanisms of conserved-charge redistribution in QCD matter by comparing the rapidity dependence of charge and baryon transport.
