Cameron Dean contributed to the sPHENIX-Collaboration/analysis repository by developing and refining particle physics analysis workflows, focusing on meson reconstruction, simulation input handling, and data quality controls. He implemented C++ modules for QCD meson selection, expanded the KFParticle framework to support new particle species, and enhanced geometric acceptance calculations for Lambda and K_S0 decays. Using C++, Bash, and the ROOT framework, Cameron streamlined DST processing, improved simulation reproducibility, and introduced database-backed luminosity counting. His work emphasized modularity, maintainability, and data integrity, demonstrated by code refactoring, exclusion of corrupted data, and disciplined code hygiene, supporting scalable and reliable high-energy physics analyses.

Apr 1, 2025In April 2025, the analysis work in the sPHENIX-Collaboration/analysis repository delivered a significant expansion of meson analysis capabilities and strengthened data quality controls. Key features include D0 tooling with Lambda-pi cascade reconstruction using a KS0 fitter, along with plotting distributions and mass fits, supported by a KS0 fitter macro to streamline decays analyses and an updated KFP example to reflect the new workflow. The changes enable Xi/Omega analyses and faster, validated results. A major data-quality improvement was implementing an exclusion of run 53879 from D0 production data to prevent corrupted data from biasing results. Overall, these updates expand physics reach, improve reliability, and demonstrate proficiency in ROOT/C++ analysis, macro/configuration management, and end-to-end workflow improvements.
