677 papers

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.

Ab initio optical potentials for magnesium isotopes: from stability to the island of inversion

This paper presents the first *ab initio* nonlocal optical potential calculations for magnesium isotopes (24,26,28,32^{24,26,28,32}Mg) using the symmetry-adapted no-core shell model and multiple-scattering theory, successfully reproducing experimental data for 24^{24}Mg and providing parameter-free predictions for heavier isotopes that validate global models near the N=20 island of inversion while highlighting their limitations.

Comment on "Lattice QCD constraints on the critical point from an improved precision equation of state"

This paper critiques a recent lattice QCD study that claims to exclude a QCD critical endpoint below μB≈450\mu_B \approx 450 MeV, arguing that the entropy-contour method used fails to directly probe critical singularities and therefore cannot provide model-independent constraints on the critical point's location.

Probing Nuclear Structure with Kaonic Atoms through E2 Resonance Mixing

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.

Sign Reversal of Boer-Mulders Functions from Semi-inclusive Deep-Inelastic Scattering to the Drell-Yan Process

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.

Interaction of accelerator neutrinos with energies up to 55 MeV with 127{}^{127}I nuclei

This study investigates the interaction of accelerator neutrinos up to 55 MeV with 127{}^{127}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.

Isolation of photon-nuclear interaction backgrounds in the search for the chiral magnetic effect in relativistic heavy-ion collisions

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.

Magnetic moments of open bottom--charm molecular pentaquark octets

This paper presents a comprehensive theoretical calculation of the magnetic moments for open heavy-flavor (bcˉb\bar{c} and cbˉc\bar{b}) 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.

Sensitivity enhancement techniques for cryogenic calorimeters in the NUCLEUS experiment

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.

Heavy-Flavor Fragmentation from HF-NRevo: Status, Prospects, and Intrinsic Charm

This paper reports on the development and application of the HF-NRevo framework, which provides a consistent perturbative description of heavy-flavor fragmentation for SS-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.
