Abstract

High-energy proton collisions can be used to study heavy particles that decay very quickly, like the Higgs boson. But long-lived particles – which travel more than a few millimeters before they decay – could be key in explaining big questions we have about our Universe. In this colloquium, I will present a case study using novel experimental approaches to hunt for long-lived heavy neutrinos using data collected by the ATLAS experiment. This talk will also discuss the landscape of heavy neutrino searches at the Large Hadron Collider and the pivotal role that designing and constructing new detectors will play in boosting searches for new physics at the energy frontier.
