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 investigates the E2 nuclear resonance effect in kaonic molybdenum isotopes using advanced Dirac-Fock calculations and updated nuclear data to demonstrate how kaonic atoms can serve as a unique probe for nuclear structure and assess the observability of this phenomenon in future experiments like EXKALIBUR.
This paper reviews the theoretical and experimental status of the predicted sign reversal of Boer-Mulders functions between semi-inclusive deep-inelastic scattering and Drell-Yan processes, demonstrating that current data supports this reversal for proton valence quarks while highlighting future prospects for testing it in pions at the Electron-Ion Collider.
This review paper outlines the physics prospects of proposed Super Tau-Charm Factories, highlighting their unique capabilities in high-luminosity electron-positron collisions to advance precision tests of the Standard Model, explore CP violation, study tau and charm properties, and investigate nonperturbative QCD phenomena.
This study investigates the interaction of accelerator neutrinos up to 55 MeV with I nuclei at the SNS, calculating cross sections that reveal the dominant contribution of the Gamow-Teller resonance GTR-1 (60–80%) alongside significant effects from higher resonances GTR-2 and AR-2, with theoretical results showing agreement with experimental data below the neutron separation threshold.
This study quantitatively assesses the contribution of coherent photon-nuclear interactions, driven by strong electromagnetic fields in relativistic heavy-ion collisions, as a distinct background source that mimics chiral magnetic effect signals to improve the precision of separating genuine CME signals from background noise.
This paper presents a comprehensive theoretical calculation of the magnetic moments for open heavy-flavor ( and ) molecular pentaquark octets within a constituent quark model, revealing distinct electromagnetic signatures that differentiate between symmetric and antisymmetric light-diquark configurations and provide crucial benchmarks for identifying these states in future experiments.
This paper presents two complementary sensitivity enhancement techniques for the NUCLEUS experiment's cryogenic calorimeters—operating point optimization and two-dimensional optimum filter analysis—which, when combined, achieved a baseline energy resolution of 2.94 ± 0.05 eV using a CaWO4 detector.
This paper reports on the development and application of the HF-NRevo framework, which provides a consistent perturbative description of heavy-flavor fragmentation for -wave quarkonia and fully heavy tetraquarks, enabling new investigations into medium effects in heavy-ion collisions and the intrinsic charm content of the proton at future collider facilities.
This paper reports the successful fabrication and first cryogenic operation of two compact n-type germanium ring-contact (GeRC) prototypes, establishing a proof-of-principle workflow for their complex non-planar geometry and demonstrating stable performance at 77 K as a foundational step toward scalable, low-background detectors for rare-event experiments like LEGEND-1000.
The East Lansing Model presents a global, Bayesian uncertainty-quantified optical potential for neutrons and protons that utilizes a novel asymmetry-dependent parameterization calibrated with (n,n), (p,p), and (p,n) experimental data to significantly reduce extrapolation uncertainties toward the proton and neutron driplines.
