This paper reports the first direct observation of three-neutron emission from He, identifying a resonance-like structure consistent with sequential decay via He and finding no evidence for a trineutron resonance or significant three-neutron correlations beyond standard two-body interactions.
This paper reviews the history of heavy-ion experiments at the CERN SPS, detailing how studies with light and lead ions from the mid-1980s to 2000 culminated in the announcement of evidence for quark-gluon plasma formation and a subsequent energy scan to determine the creation threshold.
This paper reports the successful off-line commissioning of the radio frequency quadrupole ion guide for the St. Benedict experiment, demonstrating transport efficiencies exceeding 95% from the upstream RF carpet chamber and 60% from the dedicated $90^\circ$ off-line source to facilitate future tests of the Standard Model's electroweak sector.
This paper introduces a Bayesian-inspired model-averaging framework that combines abrasion-ablation calculations from multiple nuclear mass tables to generate statistically weighted predictions and uncertainty estimates for rare-isotope production cross sections, thereby improving accuracy for both interpolation and limited extrapolation in proton-rich fragmentation regimes.
This study constrains the properties of resonances in Ca via proton scattering on an unstable K beam to refine the Ar()K reaction rate, ultimately finding that the updated rate does not significantly alter the light curve features of modeled Type I X-Ray bursts.
This paper reports the first precision mass measurements of \textsuperscript{130}Te, \textsuperscript{130}Sn, and \textsuperscript{130}Sn\textsuperscript{m} using the Phase-Imaging Ion Cyclotron Resonance technique, demonstrating improved precision for \textsuperscript{130}Sn and utilizing these new values in SkyNet simulations to refine models of r-process nucleosynthesis and distinguish between cold and hot astrophysical scenarios.
Using CMS Open Data from PbPb collisions at , this study presents preliminary measurements of the radial flow observable , confirming key collective phenomena such as long-range correlations and factorization that are consistent with ATLAS results at higher energies.
This study characterizes the light yield and transmission properties of Saint-Gobain's BCF-91A and Eljen Technology's new EJ-160 wavelength-shifting fibers under ionizing radiation, revealing that the EJ-160 variants offer significantly higher light yields (5–7 times greater) despite varying attenuation lengths.
By performing the first direct measurement of the ON reaction at astrophysical energies, researchers determined a thermonuclear rate approximately 1.5 times higher than standard values, thereby ruling out a previously suggested seven-fold enhancement and concluding that this reaction alone cannot explain observed calcium-to-sulphur and argon-to-sulphur ratio variations in Type Ia supernovae.
This paper presents the first systematic lattice QCD study of proton- scattering across multiple pion masses and lattice spacings, yielding scattering parameters and cross sections that agree with experimental data and confirm attractive interactions critical for nuclear theory and neutron star modeling.
This paper introduces VarP-GP, a cost-efficient Bayesian emulator that leverages variable statistical precision in Monte Carlo simulations to significantly reduce uncertainty in quark-gluon plasma modeling, thereby enabling previously infeasible multi-model calibrations of high-energy nuclear collision data.
This review provides a unified account of the four-decade-long heavy-ion physics programme conducted by the NA35, NA49, and NA61/SHINE experiments at the CERN SPS, highlighting their collective contributions to the search for the quark-gluon plasma and the characterization of the transition between different regimes of strongly interacting matter, while also including personal recollections.
This study utilizes an improved multi-phase transport model to analyze Pb+Pb collisions at the LHC, finding that while anisotropic flow measurements can exclude large neutron skins in Pb, they exhibit a geometric degeneracy that limits their ability to precisely distinguish between zero and moderate neutron skin values.
Using an ab initio approach combining the multi-reference in-medium similarity renormalization group and the quantum-number projected generator coordinate method with chiral two- plus three-nucleon interactions, this study systematically reproduces the low-lying properties of neutron-rich nuclei around and delineates the specific boundaries of the island of inversion.
This paper demonstrates that -decay half-lives serve as a novel and effective probe for the emergent magic number , revealing a pronounced shell gap in Calcium and Potassium isotopes while indicating its absence in Argon and Chlorine.
This paper evaluates experimental nuclear structure data for the previously unobserved, three-proton-unbound nucleus 20Al, which was recently discovered via charge-exchange reactions and characterized by its one-proton decay to the unbound ground state of 19Mg.
This paper demonstrates that the Richardson-Lucy algorithm effectively reconstructs three-dimensional pion emission sources from heavy-ion collision data, revealing their sensitivity to the initial neutron skin thickness and establishing the method as a viable tool for probing neutron density distributions in heavy nuclei.
Using the STAR experiment at RHIC, researchers observed significant sequential suppression of charmonium states in Ru+Ru and Zr+Zr collisions at 200 GeV, demonstrating that the larger (2S) meson is suppressed more strongly than the J/ meson with a 5.6 standard deviation significance.
This study presents a precision measurement of bremsstrahlung gamma rays in Sn+Sn collisions at 25 MeV/u using the CSHINE spectrometer, establishing a robust experimental framework to extract a high momentum tail fraction of and demonstrating the feasibility of probing short-range correlations in low-energy heavy-ion reactions.
The JETSCAPE Collaboration employs Bayesian Inference with Active Learning to determine the jet transport parameter in the Quark-Gluon Plasma by simultaneously analyzing inclusive hadron and jet suppression data from RHIC and LHC, revealing systematic tensions that offer new insights into jet transport physics.
