Introduction: Logan is a rising 4th-year Bachelors student at a Liberal Arts College called Pacific University in Forest Grove, Oregon, USA. He is double majoring in Physics and Mathematics and believes his career path is guiding him toward theoretical particle cosmology.

Abstract: The Compact Muon Solenoid (CMS) detector records, at its peak, around 1 billion interactions per second (CMS Collaboration), which, over time, is way too much data to hang on to long-term. This is why CMS utilizes detector components called triggers, which sift through and decide whether or not to keep data. This project focuses on a more detail-oriented trigger, the High-Level Trigger (HLT) looking for an unobserved interaction: W-Boson decay into three charged pions. More specifically, we are analyzing the efficiency of triggers looking for this interaction to see if we can find a replacement for the DeepTau HLT trigger algorithm..
