Reduced event tables and analysis code for "Neutron response and fragmentation-resolved baryon partitioning in deformed uranium collisions"
Year: 2026
Type: article
Abstract: This dataset contains the reduced event tables, analysis products, verification scripts, and fragmentation-generator patch used in “Neutron response and fragmentation-resolved baryon partitioning in deformed uranium collisions.” The deposit contains 39 CSV tables from 740,000 simulated U+U collision events at √s_NN = 193 GeV. It covers spherical and deformed uranium densities, G4/ABLAXX/repaired-AAMCC fragmentation and evaporation chains, detector resolution controls, nucleon-nucleon cross-section controls, independent random seeds, and a scan of the MST critical distance. The analysis converts the free-neutron partition into a response fraction relative to the baryon-number partition, providing a measurable diagnostic of the spectator fragmentation history. The reduced-data analysis requires Python and NumPy; the generator patch requires the upstream AAMCC snapshot, Geant4 10.4.0, and ROOT 6.14/04. The records are simulated data, not event-level measurements. No complete upstream AAMCC source is redistributed because the supplied snapshot contains no upstream license file.
