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.

One- and three-dimensional identical charged-kaon femtoscopic correlations in Pb--Pb collisions at sNN=5.02\mathbf{ \sqrt{s_\mathrm{NN}}=5.02} TeV

This paper presents measurements of identical charged-kaon femtoscopic correlations in Pb-Pb collisions at sNN=5.02\sqrt{s_{\rm NN}} = 5.02 TeV, revealing that the extracted emission source radii decrease with increasing collision centrality and pair transverse momentum—a trend attributed to collective flow and well-described by hydrokinetic models, which also indicate that kaons are emitted earlier in more peripheral collisions.

Space-time evolution of particle emission in p$-$Pb collisions at sNN= 5.02\mathbf{\sqrt{s_{\rm NN}}=~5.02} TeV with 3D kaon femtoscopy

This paper presents the first measurement of three-dimensional femtoscopic correlations between identical charged kaons in p$-$Pb collisions at sNN=5.02\sqrt{s_{\rm NN}} = 5.02 TeV, revealing that source sizes increase with multiplicity and decrease with transverse momentum, align with trends in other collision systems, and indicate a kaon emission evolution comparable to peripheral Pb$-$Pb collisions.

Ionization potential of radium monofluoride

This paper reports the experimental measurement and relativistic coupled-cluster theoretical prediction of the ionization potential of radium monofluoride (RaF) as 4.969 eV, alongside an improved calculation of its dissociation energy, confirming that RaF is a unique diatomic molecule where the dissociation energy exceeds the ionization potential.

Hybrid-Contact Planar HPGe Process Vehicle Toward Ring-Contact Designs

This paper demonstrates the successful fabrication and characterization of a hybrid-contact planar HPGe detector (KL01) that combines a lithium-suspension paint process with thin-film a-Ge/Al contacts, validating a practical workflow for future scalable ring-contact designs essential for high-sensitivity rare-event searches.
