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 study investigates how global rotation in ultra-relativistic heavy-ion collisions modifies chemical freeze-out parameters within the hadron resonance gas model, revealing that rotation systematically lowers freeze-out temperatures and suggesting that hadron yield ratios are more sensitive indicators of these rotational effects than conventional cumulant ratios.
This study quantitatively assesses the contribution of coherent photon-nuclear interactions, driven by strong electromagnetic fields in relativistic heavy-ion collisions, as a distinct background source that mimics chiral magnetic effect signals to improve the precision of separating genuine CME signals from background noise.
This paper presents a comprehensive theoretical calculation of the magnetic moments for open heavy-flavor ( and ) molecular pentaquark octets within a constituent quark model, revealing distinct electromagnetic signatures that differentiate between symmetric and antisymmetric light-diquark configurations and provide crucial benchmarks for identifying these states in future experiments.
This paper presents two complementary sensitivity enhancement techniques for the NUCLEUS experiment's cryogenic calorimeters—operating point optimization and two-dimensional optimum filter analysis—which, when combined, achieved a baseline energy resolution of 2.94 ± 0.05 eV using a CaWO4 detector.
This paper reports on the development and application of the HF-NRevo framework, which provides a consistent perturbative description of heavy-flavor fragmentation for -wave quarkonia and fully heavy tetraquarks, enabling new investigations into medium effects in heavy-ion collisions and the intrinsic charm content of the proton at future collider facilities.
This paper reports the successful fabrication and first cryogenic operation of two compact n-type germanium ring-contact (GeRC) prototypes, establishing a proof-of-principle workflow for their complex non-planar geometry and demonstrating stable performance at 77 K as a foundational step toward scalable, low-background detectors for rare-event experiments like LEGEND-1000.
The East Lansing Model presents a global, Bayesian uncertainty-quantified optical potential for neutrons and protons that utilizes a novel asymmetry-dependent parameterization calibrated with (n,n), (p,p), and (p,n) experimental data to significantly reduce extrapolation uncertainties toward the proton and neutron driplines.
This paper non-perturbatively evaluates the parity-violating spin asymmetry and its QED corrections for elastic electron scattering from spin-zero nuclei across a wide energy range, demonstrating that low-lying nuclear excited states significantly impact low-energy backward-angle scattering but yield negligible dispersive contributions at GeV energies relevant to the PREx experiment.
This paper employs a symmetry-preserving vector-vector contact interaction to calculate the four kaon transverse momentum dependent parton distribution functions (TMDs), offering insights into the roles of emergent hadron mass, Higgs-boson coupling effects on strange quark mass, gauge link models regarding positivity constraints, and scale-evolution impacts on the Boer-Mulders function.
This paper presents a parameter-free microscopic multiple scattering model based on the distorted-wave approximation and ab initio nuclear densities to successfully describe inelastic proton scattering off C across a range of energies, demonstrating the reliability of extending elastic scattering formalisms to inelastic transitions.
