Title: From classifier to bump hunt: methods in resonant anomaly detection
26. June 2025 - Physik West SE 22.00.0177 - 2:15 p.m.

Resonant anomaly detection (RAD) methods have been developed to enhance the sensitivity of traditional bump hunt searches. The main components of these methods are the use of a background template to train a classifier, which assigns an anomaly score to events, and a subsequent statistical analysis of the data points that survive a selection based on this score. After introducing the general idea behind RAD, we present two methods developed in this context - CWoLA and CATHODE - which we use to illustrate the application of ML tools to produce both the classifier and the background template.
