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 utilizes Fourier-Bessel transformations of exclusive meson production cross sections from photon-proton collisions to reveal that the proton's baryon number is concentrated in a transverse radius of 0.33–0.53 fm, which is significantly smaller than the proton's charge and mass radii.
This study presents high-precision excitation functions for proton-induced reactions on natural molybdenum targets in the 13–22 MeV energy range, resolving previous data discrepancies for specific technetium isotopes and providing a comprehensive covariance analysis for medical isotope production.
This paper identifies fluorine-based compounds, particularly octafluoropropane, as optimal targets for measuring subleading axial-vector contributions in coherent elastic neutrino-nucleus scattering, demonstrating that such experiments could determine the axial coupling at the level and probe spin-dependent new physics.
Using a coupled-channels framework derived from a constituent quark model, this study predicts a rich spectrum of resonant and virtual tetraquark candidates exhibiting heavy-quark spin symmetry multiplets, with specific guidance provided for their experimental detection through characteristic decay patterns and widths.
The paper proposes a novel nuclear interferometer utilizing the thorium-229 clock transition to detect ultra-light dark matter, offering enhanced sensitivity to variations in fundamental constants and the QCD sector that could complement and surpass existing terrestrial clock experiments.
This paper presents a theoretical study using unitarized chiral interactions to calculate and correlation functions, demonstrating that the inclusion of strong scattering effects—particularly the subthreshold resonance for and the mildly repulsive force for —successfully reproduces ALICE experimental data and validates femtoscopy as a powerful tool for probing strangeness-related hadronic interactions.
This paper demonstrates that analyzing two-particle correlations in ultra-relativistic ultra-central ion-ion collisions provides a robust method for imaging ground-state two-body correlations in light nuclei, offering a superior alternative to traditional low-energy approaches based on Kumar operators.
This paper presents comprehensive perturbative QCD baseline predictions for cold nuclear matter effects in light-ion collisions at LHC energies, demonstrating that while these effects induce significant suppressions with large uncertainties, specific multi-cross-section ratios can effectively cancel these uncertainties to enhance the sensitivity to quark-gluon plasma signatures.
This paper compares two methods for eliminating Pauli-forbidden states in three-body nuclear systems—Pauli projection and supersymmetric transformation—finding that while Pauli projection better matches experimental deuteron-He scattering data, neither method demonstrates clear superiority for bound and resonant states, though systematic differences between them are observed.
A high-sensitivity search for neutron-to-mirror-neutron oscillations conducted at the PSI UCN source found no evidence of anomalous neutron losses, thereby excluding 99.98% of the previously claimed parameter space and establishing new limits on the oscillation time constant.
