Event Selection

Abstract

This analysis in this thesis uses both CC and NC samples. This chapter will discuss the procedure for event selection and the efficiencies and purities of both samples. A preselection is first discussed, followed by the specifics of the NC selection for both MINOS detectors. To ensure no double counting between selectors the CC selector is performed last and selects the CC events from the failed NC sample to ensure both samples are exclusive. The NC selector uses a simple cuts-based method, whereas the CC selector uses a kNN-based method.
