요약The MEG II experiment is an active search for the decay of a muon resulting in a positron-photon pair. The experiment plans to reach a sensitivity of 6*10-14, improving on the limit of the MEG I experiment by an order of magnitude. The MEG II detector analysis was written by the MEG II collaboration; this thesis details the detector analysis focusing on portions of the analysis I contributed to including the positron analysis and target analysis. These chapters also serve as a thorough description of the analysis for current and future collaborators. The thesis ends with a description of two physics analyses performed on the MEG II experiment's first year of physics data and demonstrates the experiment's expected performance over its lifetime.Chapter 1 is an introduction to the Standard Model of particle physics. Charged lepton flavor violation (CLFV) processes, including the process of a muon decay resulting in a positron-photon pair are realized in the Standard Model, but occur at an extremely small, undetectable, rate (branching fraction of 10-54). A variety of theoretical models beyond the Standard Model allow for CLFV (and thus the decay of a muon resulting in a positron-photon pair) at a potentially observable rate (branching fraction of 10-14). CLFV has not been observed despite extensive searches for over 50 years. It's observation would have dramatic implications on the field of particle physics. Chapter 2 discusses past and future experimental searches in the field of CLFV. Chapter 3 describes the MEG II experimental technique, including the signal/background, detectors, electronics, trigger, etc.The remaining chapters discuss MEG II analysis. One of the most critical points of the experiment is the background rejection, which is required to achieve the optimal experimental sensitivity. This background rejection is achieved via precise kinematic measurements of the positron and the photon at the stopping target. The precision of these kinematic measurements is common theme that will be discussed throughout this thesis. In Chapter 4, a novel technique used to monitor the MEG II stopping target using a camera is described along with its results. Chapter 5 presents the reconstruction of positrons in the MEG II drift chamber. The relative alignment of the MEG sub-detectors and their calibrations are discussed in Chapters 6 and 7 respectively. Chapter 8 describes the details of the physics analysis of the 2021 dataset. Conclusions are described in Chapter 9.
