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 presents a comprehensive compilation of material radioactivity constraints generated through various techniques to support the nEXO double-beta decay search, serving as a critical resource for selecting radiopure materials and avoiding duplicated efforts in low-energy rare-event experiments.
This chapter explains the origins and significance of the proton radius puzzle, which arose from a discrepancy between muonic and electronic hydrogen measurements suggesting a potential violation of lepton universality, and presents recent experimental results that have successfully resolved the issue.
This paper presents the first measurement of open-charm baryon-to-meson ratios, specifically the baseline, in + collisions at RHIC energies using the high-statistics, unbiased dataset collected by the sPHENIX experiment to investigate heavy-flavor hadronization mechanisms.
This paper summarizes the ISO-BREAK 25 workshop held in Kielce in October 2025, which reviewed the current status of isospin-symmetry breaking observed by NA61/SHINE in nucleus-nucleus collisions, discussed its confirmation by other experiments, and outlined future experimental and theoretical priorities to explain this phenomenon.
This paper presents a comprehensive leading-order NRQCD study of production in proton-proton collisions at LHC energies, demonstrating that theoretical predictions for cross-sections and ratios, including feed-down contributions, align well with experimental data from ALICE, ATLAS, CMS, and LHCb while exhibiting saturation behavior at high transverse momenta.
This paper proposes a novel high-luminosity experimental approach using tagged hyperons produced in proton-proton collisions within a nested-target setup to precisely measure hyperon-nucleon interactions, thereby addressing the uncertainties in the equation of state that underlie the hyperon puzzle in neutron stars.
This study utilizes the PHQMD approach with a novel momentum-dependent potential to demonstrate that a soft, momentum-dependent nuclear equation of state best reproduces experimental flow data for protons and light clusters in intermediate-energy heavy-ion collisions, while also revealing distinct flow signatures that can help discriminate between different cluster formation mechanisms.
Using a multi-source thermal model, this paper argues that the valence quark-stopping scenario is more suitable than the gluon junction scenario for explaining baryon number transport in high-energy collisions, a conclusion that can be further validated by future electron-nucleus collision experiments at the Electron-Ion Collider.
The BABY 1L experiment successfully benchmarked tritium breeding in a scaled-up molten salt system under DT neutron irradiation, demonstrating a six-fold improvement in breeding ratios over previous tests, validating OpenMC simulations, and identifying diffusion-limited transport and hydrogen-facilitated release as key mechanisms for future fusion power plant designs.
Using a sample of events collected by the BESIII detector, this study reports the first observation of the antihyperon-nucleon annihilation processes and , measures their cross sections, and provides evidence for the resonance in the spectrum.
