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 introduces a physics-embedded Bayesian neural network (PE-BNN) framework that integrates an energy-independent phenomenological shell factor and WAIC-based hyperparameter optimization to accurately predict energy-dependent fission product yields with fine structures and close agreement with known nuclear shell effects.
This paper investigates how magnetic fields in heavy ion collisions induce quarkonia spin alignment through both orbital wave function distortion and spin state mixing, finding that the spin contribution dominates phenomenologically while the subleading orbital effect offers a unique probe for studying quarkonium structural changes.
This paper describes the design and construction of the BUTTON-30, a 30-tonne hybrid detector installed 1.1 km underground at the Boulby Laboratory to evaluate the potential of simultaneous Cherenkov and scintillation light detection for neutrino interactions in a low-background environment.
This paper presents the first experimental measurement of the strong interaction scattering parameters for the and systems using femtoscopic correlation functions from Pb--Pb collisions at TeV recorded by ALICE, providing crucial benchmarks for low-energy chiral QCD dynamics.
This paper analyzes the missing-energy spectrum from monochromatic neutrino-C interactions measured by the JSNS collaboration using a relativistic distorted-wave approach with an improved spectral function, while discussing the roles of nuclear recoil, final-state interactions, and neutrino event generators in describing low-energy nuclear effects.
This paper summarizes the achievements of the MexNICA Collaboration, established in 2016 to coordinate Mexican participation in the MPD-NICA experiment at JINR, highlighting their contributions to the development of the miniBeBe trigger detector and advances in phenomenological and theoretical studies of the baryon-rich QCD phase diagram.
This paper presents a simultaneous analysis of measured and calculated data to predict the prompt fission neutron spectra (PFNS) of 233U(n,F) up to 20 MeV, establishing that while its spectrum is harder than 235U(n,F) but softer than 239Pu(n,F), the underlying pre-fission contributions and energy partitioning differ significantly due to fissility and competing reaction channels.
This paper utilizes state-of-the-art lattice calculations and experimental form factor data to visualize momentum flow and color-Lorentz forces within the nucleon, revealing that the gluon anomaly generates a critical attractive force on quarks comparable in strength to heavy-quark confinement.
The MAGNETO- experiment utilized a high-statistics measurement of Pu decays with metallic magnetic calorimeters to find no evidence for keV-scale heavy neutral leptons, thereby establishing an upper limit of at 95% confidence for an 11.5-keV HNL mixing with the electron neutrino.
This paper proposes a novel, decentralized approach to securing the domestic supply of the medical isotope Mo by adapting high-current deuterium cyclotrons, originally designed for neutrino research, to generate sufficient neutrons for isotope production without relying on nuclear reactors or highly enriched uranium.
