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 demonstrates that longitudinally polarized protons can induce chirality in the final states of intermediate-energy reactions involving non-coplanar momenta, a phenomenon quantified by the analyzing power and explained through the coupling of incident proton helicity to the orbital chirality of single-particle wave functions.
This paper reports a nearly two-orders-of-magnitude improvement in the precision spectroscopy of an inner-shell orbital clock transition in neutral ytterbium using a three-dimensional magic-wavelength optical lattice, enabling high-precision isotope shift measurements that set new bounds on hypothetical boson-mediated forces and advance applications in quantum science and new physics searches.
The GlueX experiment at Jefferson Lab reports the first observations of and photoproduction alongside production, revealing forward-peaked angular distributions consistent with Regge-like -channel exchanges and a phenomenological double-exchange model, while finding no narrow resonant structures and observing a suppression of pairs similar to other reactions.
This paper extends a newly introduced framework for single-diffractive hard exclusive processes to the specific case of exclusive real-photon electroproduction, offering a more systematic and transparent approach for extracting generalized parton distributions (GPDs) from experimental data.
This paper proposes that fusion systems can achieve economic viability well before reaching energy breakeven by co-producing high-value isotopes through neutron-driven transmutation, thereby creating a revenue-positive pathway that scales from small-scale medical radioisotope production to large-scale electricity and gold generation.
This paper investigates elastic proton-proton and pion-proton scattering within the framework of holographic QCD by modeling Pomeron and Reggeon exchanges as Reggeized spin-2 glueball and vector meson propagators, respectively, and demonstrates that the resulting total and differential cross sections, including Coulomb interactions, align well with experimental data across a wide kinematic region.
This paper develops a Bayesian inference framework to disentangle genuine collective flow from transverse momentum conservation (TMC) backgrounds in small collision systems, revealing that while +Pb data aligns with standard flow measurements, + collisions require this new method to accurately extract flow magnitudes that are otherwise underestimated due to competing TMC effects.
Motivated by color coherence and decoherence effects, this paper proposes a theoretical framework combining vacuum-like evolution and medium-induced radiation to successfully describe the inclusive jet modification factor and its substructure dependence in 0–10% PbPb collisions at as measured by ATLAS.
This study demonstrates that updating specific (, n) reaction rates, particularly for O and Ne, significantly enhances the weak s-process yields in metal-poor massive stars by tens of times, with the O(, n) reaction playing a dominant role across all evolutionary stages, especially in more massive models.
The TUCAN collaboration reports significant progress in commissioning its high-intensity accelerator-driven ultracold neutron source and developing the associated spectrometer, achieving the first UCN production in 2024 and setting the stage for a neutron EDM experiment with a sensitivity goal of and two orders of magnitude improved statistics.
