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 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 study presents the first measurement of the astrophysical S-factor for the Sm(p,)Eu reaction at Gamow window energies using the activation technique, demonstrating satisfactory agreement with theoretical predictions from TALYS and NON-SMOKER codes to facilitate the calculation of relevant astrophysical reaction rates.
This paper presents the physical thickness characterizations of FRIB production targets with various nominal thicknesses, measured using a custom-built non-contact apparatus to ensure the areal thickness variation remains within the required 2% constraint for efficient thermal dissipation and high rare isotope beam production.
This paper employs an extended stochastic variational method combined with complex scaling to compute the bound and resonant states of various muonic few-body Coulomb systems with high precision, successfully resolving previously unknown shallow resonances in three- and four-body sectors.
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.
This paper presents the first *ab initio* nonlocal optical potential calculations for magnesium isotopes (Mg) using the symmetry-adapted no-core shell model and multiple-scattering theory, successfully reproducing experimental data for Mg and providing parameter-free predictions for heavier isotopes that validate global models near the N=20 island of inversion while highlighting their limitations.
This paper critiques a recent lattice QCD study that claims to exclude a QCD critical endpoint below MeV, arguing that the entropy-contour method used fails to directly probe critical singularities and therefore cannot provide model-independent constraints on the critical point's location.
This paper demonstrates that the CITIUS high-resolution X-ray detector, through its gain-selecting architecture and substantial charge sharing enabled by long carrier drift distances, achieves significantly improved spatial resolution for imaging heavy charged particles and neutrons, as validated by experimental irradiation with alpha particles and Geant4 simulations.
