Worked on enhancing photon analysis precision within the SegmentLinking/cmssw repository by increasing the decimal precision for the pfChargedIso and hoe shower shape observables in the photon analysis configuration. This Python-based update focused on improving data quality for the Hgg analysis, enabling more robust signal discrimination and reliable physics results. The change was implemented at the configuration level in photons_cff.py, ensuring minimal impact on other analyses and facilitating future refinements. Leveraging skills in data analysis and physics analysis, the work emphasized clear commit traceability, supporting reproducibility and auditability while laying the groundwork for tighter photon-based selection criteria.
November 2024: Delivered a precision-focused enhancement to the photon analysis in SegmentLinking/cmssw, increasing decimal precision for two shower shape observables (pfChargedIso and hoe) in the photon analysis configuration. This improvement enhances data quality for the Hgg analysis and strengthens the reliability of photon-based selections. No major bugs fixed in this period within the scope of SegmentLinking/cmssw. Impact: Higher-quality photon observables enables tighter signal discrimination and more robust physics results for Hgg, with clear traceability through the associated commit and configuration change. Scope and alignment: Changes confined to the photon analysis configuration in Python (photons_cff.py), minimizing risk to other analyses and facilitating future refinements.
