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 reports new measurements and analysis of Adiabatic Fast Passage (AFP) efficiency in various solid polarized target materials, introducing a joint manipulated-lineshape method to extract vector and tensor polarization components and demonstrating a strong dependence of AFP efficiency on initial polarization.
This paper proposes a beam-energy scan of isobaric collisions (Ru+Ru vs. Zr+Zr) to precisely measure electric-charge transport and distinguish between competing microscopic mechanisms of conserved-charge redistribution in QCD matter by comparing the rapidity dependence of charge and baryon transport.
The paper introduces JetPrism, a configurable Conditional Flow Matching framework that addresses the misleading nature of standard training losses in nuclear physics simulations by establishing a multi-metric evaluation protocol to ensure generative models achieve true physical fidelity and convergence beyond generic loss indicators.
The STAR experiment at RHIC presents high-statistics femtoscopy results from Isobar and Au+Au collisions, revealing an attractive interaction in - pairs and a bound state in - pairs through the analysis of final-state correlations.
This paper refines theoretical predictions for light-by-light scattering by improving two-loop helicity amplitudes with asymptotic expansions and Coulomb resummation, providing state-of-the-art Standard Model cross-section calculations and a new Monte Carlo event generator named LbLatNLO.
This paper presents continuum-estimated (2+1)-flavor lattice QCD results demonstrating that the baryon-electric charge correlation serves as a sensitive magnetometer for strong magnetic fields, while also mapping the equation of state up to and constructing detector-compatible observables to bridge theoretical predictions with experimental heavy-ion collision data.
This paper investigates the photoproduction and nuclear absorption of charmonium on C and W targets near the kinematic threshold using a collision model with nuclear spectral functions, demonstrating that calculated observables are sensitive to absorption scenarios and could help determine the -nucleus cross section for future experiments at the CEBAF facility.
This paper establishes an analytical connection between triaxial nuclear shapes and three-particle correlations in relativistic heavy-ion collisions, demonstrating that specific flow and momentum fluctuation observables are directly proportional to the nuclear triaxiality parameter .
This paper presents a low-order analytical framework demonstrating that lithium-based tritium breeding and heat-removal systems in fusion reactors exhibit Bessel-type dynamics, enabling the effective application of PID controllers to manage thermal expansion and tritium inventory errors.
This paper introduces a generalizable foundation model for calorimetry that leverages next-token transformer architectures combined with Mixture-of-Experts pre-training and parameter-efficient fine-tuning to enable modular, scalable, and computationally efficient simulation of particle showers across diverse materials and detector configurations without catastrophic forgetting.
