We have a great mathematical model for how the known elementary particles interact, but there are phenomena such as dark matter that it doesn't explain. New particles light enough to be created at the LHC could resolve many of these issues. We have been looking in LHC data for dark matter and other new particles for years, and found nothing, but we have historically focused our searches on the most obvious places. There are equally plausible but harder to access corners which are gaining momentum as search targets today. The most interesting involve "long-lived" particles (LLPs): particles that can travel a measurable distance in the detector before decaying to dark matter and/or other objects. Our search program looking for LLPs is still growing, with many places where investment in technical improvements could pay off with big leaps in discovery potential. This seminar will discuss the methods and challenges involved in doing these searches and what makes them the most exciting targets for the LHC Run 3.
