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 63-day cosmic-ray scattering experiment using Resistive Plate Chambers to simultaneously measure secondary cosmic-ray composition with high precision and establish stringent constraints on muon-philic dark matter scattering cross-sections.
This paper demonstrates for the first time that neural simulation-based inference (NSBI) can effectively constrain proton parton distribution functions using high-dimensional, unbinned LHC data, achieving significantly improved precision over traditional binned analyses by fully exploiting statistical power and reducing reliance on coarse uncertainty approximations.
This study determines the properties of key resonances in Ne using experimental angular distributions and theoretical modeling to refine the F()O reaction rate, revealing that previous estimates significantly underestimated the associated uncertainties for classical nova positron production.
This paper presents a data-driven comparative analysis of various statistical distance metrics and normalizing functions using electron and photon events from a decaying Kr-83 isotope to evaluate the stability of a dimensionless Parameter of Interest under different conditions.
This review article examines the theoretical foundations and experimental strategies for searching for neutrinoless double beta decay, summarizes current results and detection techniques, and outlines future technological advances required to achieve the sensitivity necessary to confirm this rare phenomenon.
This paper presents a global Bayesian analysis of unpolarized quark transverse-momentum-dependent parton distribution functions using Drell-Yan data at and accuracy, leveraging AI-driven functional form selection and machine-learning emulators to enable efficient Markov Chain Monte Carlo sampling and quantify uncertainties.
The ATLAS experiment measured the differential cross sections of coherent exclusive production in ultraperipheral Pb+Pb collisions at TeV using 2023 data, finding results consistent with theoretical predictions but in tension with previous Run-2 measurements in the central rapidity region.
This paper reviews recent STAR experiment results on net-proton multiplicity fluctuations from RHIC BES-II collisions to search for the QCD critical point by comparing fourth-order cumulant and factorial cumulant ratios with non-critical theoretical models while addressing initial volume fluctuations and outlining future research directions.
Using chiral effective field theory interactions and the time-dependent coupled-cluster method, this study reveals that two-particle-two-hole excitations in O and Ca nuclei generate small-amplitude, fast, short-ranged, and stochastic density fluctuations.
This paper summarizes recent STAR collaboration results on heavy-ion collisions, covering topics such as jet and quarkonium modification in quark-gluon plasma, collective dynamics, low-energy and small-sized collisions, and vector meson production, while concluding with an outlook on the upcoming data-analysis era.
