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 the characterization of a 28 nm CMOS ASIC for particle tracking detectors that integrates in-pixel analog signal processing and an on-chip neural network classifier to achieve low noise, high linearity, and effective data reduction with 99.06% agreement between hardware measurements and offline predictions.
This paper presents a systematic Bayesian validation of generative diffusion models for inpainting missing calorimeter data in relativistic heavy-ion collisions, demonstrating their effectiveness in reconstructing energy response, spatial accuracy, and uncertainty calibration across various collision centralities and mask sizes.
By analyzing charge-changing cross-section data across various targets, this study demonstrates that using heavy targets like lead eliminates the need for empirical scaling factors, making them the optimal choice for determining the proton distribution radii of unstable nuclei.
This paper reports the development and characterization of a novel 10 mol% rubidium-doped CsI scintillator crystal, which utilizes intrinsic Rb beta-decay to enable high-efficiency source-in-detector spectroscopy for investigating forbidden beta-decay mechanisms and searching for keV-scale sterile neutrinos.
This study investigates the spatial sizes of neutron and proton single-particle orbitals in calcium and scandium isotopes using nucleon knockout reactions at 230 MeV/nucleon, revealing that the 1p neutron orbitals are consistently 0.48–0.78 fm larger than the 0f7/2 orbitals while the evolution of valence proton orbital sizes remains inconclusive due to statistical uncertainties.
This study demonstrates that incorporating nuclear drip-line physics into nuclear statistical equilibrium models significantly alters the composition of supernova matter by enhancing the formation of extremely neutron-rich light clusters, thereby reducing free-neutron density and the charge fraction of heavy nuclei.
The STAR Collaboration's measurements of baryon-to-charge ratios and net-proton yields in isobar and photonuclear collisions disfavor the conventional valence quark model of baryon number conservation, providing evidence that supports the alternative baryon junction hypothesis.
By analyzing STAR experimental data on net-charge yield differences in 200 GeV Ru+Ru and Zr+Zr collisions using the UrQMD model, this study extracts a relative neutron-skin thickness difference of fm and demonstrates that initial-state nuclear geometry significantly influences baryon transport observables without requiring a baryon junction hypothesis.
This paper presents a new quantum model demonstrating that bremsstrahlung emission in the ternary fission of Cf is highly sensitive to the process's geometry and dynamics, particularly the relative motion of heavy fragments, with theoretical predictions aligning well with preliminary experimental data.
This paper proposes a method to significantly reduce the uncertainty in nuclear matrix elements for neutrinoless double-beta decay by utilizing a phenomenological effective axial-vector coupling derived from measured two-neutrino double-beta decay half-lives, thereby refining the constraints on the effective neutrino mass.
