Abstract: With the lack of evidence for new physics from the LHC’s Run 2 dataset so far, it is essential that we leave no corner of phase space unexplored. In this talk, I will discuss a recent result from the ATLAS Experiment looking for leptons with large impact parameters. This result provides unique sensitivity to sleptons with lifetimes between 0.001 and 10 ns in Gauge-Mediated Supersymmetry Models for the first time at the LHC, improving upon previous limits by almost an order of magnitude. I will also discuss trigger limitations in searches for long lived particles, and how the planned upgrades to the LHC detectors might be able to improve the situation.
