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.

A Novel, Steerable, Low-Energy Proton Source for Detector Characterization

This paper reports on the successful conversion of the Manitoba II mass spectrometer into a versatile, steerable low-energy proton beam facility (25–35 keV) capable of characterizing silicon detectors for BSM searches like the Nab experiment by delivering a monoenergetic pencil beam with a 0.6–1.26 mm spot size over a 117 mm area.

Anisotropic time evolution of sound modes in Bjorken expanding holographic plasma

This paper numerically investigates the time evolution of sound modes in a Bjorken-expanding N=4\mathcal{N}=4 Super-Yang-Mills plasma, revealing how longitudinal expansion-induced anisotropy splits the speed of sound into two distinct values and constructing an anisotropic hydrodynamic framework to interpret these findings for heavy-ion collision data.

Dark Matter-Induced Nuclear De-Excitation at SBND with Ab Initio Nuclear Theory

This paper demonstrates that the Short-Baseline Near Detector (SBND) can probe previously unexplored light dark matter parameter spaces by detecting MeV-scale photon "blips" from nuclear de-excitation, utilizing state-of-the-art ab initio nuclear theory to predict signals from argon excited states up to 18 MeV.

Jet-associated Balance Functions of Charged and Identified Hadrons in pp Collisions at s=13.6\sqrt{s}=13.6 TeV using PYTHIA8

This study utilizes PYTHIA8 to analyze charge balance functions of identified hadrons in high-multiplicity jets at s=13.6\sqrt{s}=13.6 TeV, revealing a narrowing balancing width and species-dependent dynamics that suggest multiparton interactions and color reconnection can generate collective-like features within small systems.

Sensitivity of the CUPID experiment to 0νββ0νββ decay of 100^{100}Mo

This paper presents a numerical sensitivity study for the CUPID experiment's search for neutrinoless double-beta decay of 100^{100}Mo, establishing a Bayesian exclusion limit of T1/2>1.6×1027T_{1/2} > 1.6 \times 10^{27} years and a Frequentist 3σ\sigma discovery sensitivity of T1/2=1.0×1027T_{1/2} = 1.0 \times 10^{27} years under its baseline operational scenario.
