  "abstract": "<p>This thesis presents a systematic investigation of beam-induced background effects in the electromagnetic calorimeter of the Belle II experiment, focusing on how machine conditions propagate to detector observables and reconstructed physics quantities. By correlating trigger-level observables with the &pi;\u2070 mass resolution, the study demonstrates that the mean number of out-of-time crystals and the time since last injection jointly provide a robust characterization of background conditions and their impact on data quality. These results establish that trigger-level information can serve as an early diagnostic of physics performance and provide guidance for optimizing detector operation under high-luminosity conditions.</p>",
