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.

Existence of nuclear modifications on longitudinal-transverse structure-function ratio

This paper challenges the common assumption that nuclear modifications do not exist in the longitudinal-transverse structure-function ratio RNR_N by demonstrating theoretically and numerically that nucleon transverse motion within nuclei induces such modifications, particularly in medium- and large-xx regions, which are crucial for precise nucleon structure function determination and future investigations of gluon dynamics.

Beam Energy Measurement using a Bayesian Approach with the Stacked Foil Method

This paper presents a robust Bayesian method for measuring proton beam energy at a medical cyclotron using the stacked foil technique and 48^{48}V activity, demonstrating its accuracy, uncertainty handling, and suitability for diverse experimental conditions without relying on direct charge measurements.

Design and development of optical modules for the BUTTON-30 detector

This paper details the design and construction of the watertight optical modules for BUTTON-30, a neutrino detector demonstrator located in the STFC Boulby underground facility that aims to test gadolinium-loaded water-based liquid scintillator for future large-volume observatories and nuclear reactor monitoring.

Three-body resonances of ααMααM clusters (M=ϕM=ϕ, J/ψJ/ψ, ηcη_c) in M8Be^{8}_{M}{\mathrm{Be}} nuclei

This study investigates the structural effects of ϕ\phi, J/ψJ/\psi, and ηc\eta_c mesons on 8^8Be nuclei using HAL QCD potentials and the Gaussian expansion method, revealing that the ϕ\phi meson strongly binds the system into stable states while J/ψJ/\psi and ηc\eta_c interactions are weaker and form only shallow bound states, with specific predictions for new α\alpha-charmonium bound states and the non-Borromean nature of J/ψ8Be^{8}_{J/\psi}\text{Be}.

Skewness-dependent moments of the pion GPD from nonlocal quark-bilinear correlators

This paper presents lattice QCD calculations of the odd Mellin moments of the pion valence-quark generalized parton distribution up to fifth order across a range of skewness values, utilizing boosted pion states and advanced renormalization techniques to extract skewness-dependent moments through polynomiality-constrained fits.
