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 proposes and validates a practical methodology to eliminate biases in global polarization measurements caused by asymmetric detector acceptance in fixed-target heavy-ion collision experiments, thereby enabling more accurate studies of spin dynamics across the QCD phase diagram.
This paper reports the implementation of a room-temperature thorium-229 optical nuclear clock embedded in a calcium fluoride crystal that achieves high stability through rapid laser feedback, enabling competitive constraints on ultralight dark matter models by surpassing previous limits on strong force and quark couplings.
This paper proposes an enhanced recursive gated cyclic residual-sparse linear attention network for CLYC detectors that achieves high-accuracy neutron-gamma pulse shape discrimination (98.7% accuracy, 2.2 quality factor) with robust noise resistance and ultra-low latency (0.05 ms) suitable for real-time embedded deployment.
By combining Bayesian inference with hydrodynamic simulations and Large Hadron Collider data from Xe-Xe and Pb-Pb collisions, researchers successfully reconstructed the nearly maximally triaxial ground-state shape of the Xe nucleus, thereby establishing high-energy collider experiments as a quantitative tool for probing proton-neutron correlations driven by quantum chromodynamics.
This paper presents a sensitivity-matrix-based optics correction scheme and an improved one-turn map measurement method that successfully reduced the horizontal beta beat by 10% and enhanced the reproducibility of interaction point location measurements at RHIC's IP8, providing a foundation for future control systems at the Electron-Ion Collider.
This paper investigates the dependence of two-particle azimuthal correlations on the forward rapidity gap width in 8.16 TeV pPb collisions to determine if collective flow signatures persist in events enriched with photon-lead and pomeron-lead interactions, comparing the results against previous measurements and modern event generators.
This study utilizes the JAM model and a novel Centrality-Independent Genuine Cumulant Analysis (CIGAR) framework to systematically analyze higher-order proton cumulants in Au+Au collisions at high baryon densities, providing a dynamic non-critical baseline essential for the search for the QCD critical point.
This paper presents quantum-mechanical calculations demonstrating that coherent bremsstrahlung emission overwhelmingly dominates over incoherent emission in Sn+Sn scattering at 25 MeV/u, a behavior that contrasts sharply with proton-nucleus collisions and reveals a new quantum regime for studying coherent effects in heavy-ion reactions.
This paper presents the first results on baryon reconstruction from Ni+Ni collisions recorded by the mCBM demonstrator at SIS18, successfully validating the operational performance of the detector systems and the complete data chain for the upcoming high-rate CBM experiment at FAIR.
The CMS experiment reports the first measurement of charged-hadron pseudorapidity distributions in oxygen-oxygen collisions at = 5.36 TeV, revealing that while the particle density per participating nucleon in central collisions matches that of lead-lead collisions, the data exhibit deviations from simple scaling laws that highlight the significant role of collision geometry and finite-size effects in light ion systems.
