Summary, Etc.  

요약This dissertation presents a search for a light pseudoscalar Higgs boson in the H → aa → µµττ decay channel using the full Run 2 dataset collected by the CMS detector at CERN. Due to the mass difference between the Higgs boson and the pseudoscalar Higgs boson, the final state particles have a boosted topology that includes overlapping τ decays. The search is performed for the fully hadronic, semi leptonic, and fully leptonic decays of the τ leptons. DeepDiTau, a tagger trained through machine learning, is used to identify τhτh decays that are reconstructed as jets. The expected limits on σHB(H → aa → µµττ )/σSM for all channels in this search are presented.The CMS pixel tracker was prepared for Run 3 with refurbishment, installation, and commissioning periods. This dissertation presents this process along with further calibrations and the beginning of Run 3 operation. Additionally, a dedicated radiation damage study on the innermost layer of the Barrel Pixels is presented.
