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 proposes a discovery-grade framework for detecting sub-MeV dark matter by searching for correlated "satellite-line combs"—multiple weak -ray lines shifted by a common energy offset below known neutron-capture transitions—using high-resolution HPGe detectors to suppress nuclear and instrumental backgrounds.
This paper reports a wideband search for ultralight axionlike dark matter using oscillating parity-odd time-reversal-odd nuclear Schiff moments in Eu ions within a crystal, resulting in new constraints on ALP-gluon coupling strength across eight decades of mass.
This paper proposes that quarkonium suppression in heavy-ion collisions is caused by a dynamical Hawking-Unruh causal horizon formed during initial fragmentation, which instantly decouples heavy quark pairs when their bound-state radius exceeds the horizon, thereby explaining the observed suppression hierarchy and the vanishing elliptic flow without requiring thermalized medium interactions.
This paper reviews recent LHC results, highlighting the discovery of the odderon, evidence for gluon saturation in heavy-ion collisions, and the potential for detecting axion-like particles through photon-induced processes.
This paper presents a high-precision framework for predicting reactor antineutrino fluxes at underground laboratories by incorporating matter effects (MSW) through both one-dimensional and three-dimensional Earth models, aiming to quantify the impact of Earth's structural features on flux accuracy as geoneutrino measurements approach sub-percent precision.
Using a large sample of events collected by the BESIII detector, this study reports the first observation and measurement of the cross sections for the and reactions via -nucleus scattering at an electron-positron collider.
This paper presents a comprehensive phenomenological analysis of the Ho calorimetric electron capture spectrum from the HOLMES experiment, modeling the unfolded data as a sum of Breit-Wigner resonances and shake-off continua to accurately describe spectral features, validate against theoretical calculations, and provide a robust framework for future neutrino mass experiments.
To support the BES-II program at RHIC, the STAR experiment implemented a complementary dual real-time framework combining a High Level Trigger for online event selection and an Express Data Production system for rapid, near offline-quality reconstruction, enabling prompt physics analysis and demonstrating scalability for future high-luminosity experiments.
This paper introduces an improved two-parameter analytical model for paralyzable radiation detectors that accounts for finite discriminator response time, offering superior accuracy in describing count rate relations, enabling independent parameter determination, and providing effective post-acquisition pile-up correction that allows for significantly faster data acquisition without compromising accuracy.
The paper reports the successful offline commissioning of the St. Benedict gas catcher at the University of Notre Dame, demonstrating over 95% transport efficiency for radioactive ion beams at pressures of 66 mbar and lower to support future precision measurements of mirror nuclide decay transitions.
