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 memoir dedicated to Mannque Rho recounts the author's journey into hadron physics in dense matter, clarifies the original intent behind Brown-Rho scaling, and discusses recent refinements to the theory involving chiral symmetry and -breaking effects.
This review examines recent *ab initio* calculations of finite nuclei to demonstrate how specific observables, such as neutron-skin thicknesses, electric dipole polarizabilities, and monopole sum rules, can be used to constrain the equation of state and bulk properties of nuclear matter.
This paper presents a new theoretical approach using spectral function representation and phenomenological Light-Front wave functions to calculate pion parton distribution functions, revealing that the valence region is dominated by a highly virtual quark-antiquark cluster with minimal residual mass, a configuration that successfully reproduces the observed behavior at the limit and links the PDF's peak characteristics to its analytic behavior near unity.
This paper presents the first dihadron correlation measurements in light-ion (OO and Ne--Ne) collisions at TeV with ALICE, revealing multiplicity-dependent modifications and a suppression of away-side yields in OO collisions that are qualitatively consistent with jet-medium interactions, though the potential contributions of event-selection biases and cold-nuclear-matter effects remain an open question.
This chapter in the Encyclopedia of Nuclear Physics offers a comprehensive pedagogical overview of nuclear fission, covering its theoretical foundations from macroscopic and microscopic models to modern dynamics, experimental techniques, and its critical applications in energy, astrophysics, medicine, and security, while highlighting current open questions in the field.
This paper presents the first direct measurements of the radiogenic and muon-induced neutron background at the shallow-underground Colorado Underground Research Institute (CURIE), characterizing the local neutron flux to provide essential quantitative input for planning future low-background experiments.
This paper presents ALICE measurements of anisotropic flow in O and Ne collisions using multi-particle cumulants, including the first reconstruction of the elliptic flow probability distribution and the first measurement of the ratio in light-ion systems, to investigate the influence of well-constrained nuclear geometry on collective dynamics.
This paper extends a previous study by constructing effective shell-model decay operators for neutrinoless double-beta decay in Ca, Ge, and Se up to next-to-next-to-leading order, including for the first time three-body current contributions at next-to-next-to-next-to-leading order, to evaluate theoretical uncertainties arising from both model space limitations and chiral expansion truncation.
This paper demonstrates that foundation models trained on multi-modal data significantly outperform traditional methods in reconstructing charged particles and identifying them within Time Projection Chamber datasets, while also showing adaptability to diverse downstream physics tasks.
The paper proposes a novel, waste-free nuclear energy cycle for advanced propulsion and power generation that utilizes abundant lithium and deuterium-tritium fusion, where primary lithium-6 fission triggers secondary fusion and lithium-7 fission reactions to produce stable byproducts.
