In modern high-energy physics experiments like ATLAS, the trigger system plays a crucial role in selecting which events are saved for further analysis. Traditionally, these triggers are designed to capture well-understood Standard Model signatures. However, rare or unexpected signals may evade such targeted selections.

This project focuses on calibrating a novel anomaly detection (AD) trigger—a powerful tool designed to tag unusual events that don't necessarily fit into pre-defined physics categories. I will walk you through how we study its behavior, identify overlaps with standard triggers, and build a calibration framework that will help reduce systematic uncertainties in future BSM searches..
