Search for long-lived particles in events with a displaced vertex using the ATLAS detector with the full Run2 dataset

Abstract

A large number of physics models beyond the Standard Model predict the existence of new, massive, long-lived particles. Searches for these particles rely on the detection of the decay products at a significant distance from the collision point. This signature provides interesting technical challenges due to their special reconstruction requirements as well as their unusual backgrounds. Recent results are presented on the search for long-lived SUSY particles using a displaced vertex in association with jets with the ATLAS full Run 2 data.
