Ke Kimura developed advanced muon polarization analysis features for the AliceO2Group/O2Physics repository, focusing on histogram design and variable management using C++ and data analysis techniques. Over two months, Kimura introduced new histograms for dimuon polarization studies, including mass, transverse momentum, and azimuthal angle (PhiVP), and implemented the calculation of muon pair production rate asymmetry. Enhancements included defining and managing the cosPhiVP variable and refining histogram binning to improve analysis granularity, particularly for Pb-Pb collisions. Kimura’s work strengthened the reproducibility and precision of polarization studies, demonstrating depth in high energy physics data workflows and collaborative C++ development.
