Particles beyond the Standard Model can generally have life times that are long compared to Standard Model particles at the weak scale. When produced at the Large Hadron Collider, such long-lived particles can decay far from the primary interaction vertex and possibly themselves interact with the detector material, leading to a wide variety of detector signatures. Such long- lived particle signatures are distinctly different from those associated with searches for promptly decaying beyond-the-Standard Model particles that constitute the bulk of searches for new physics at the Large Hadron Collider, often requiring dedicated analysis and reconstruction techniques. This contribution will provide an overview for searches for long-lived particles performed by the ATLAS Collaboration and present latest results using 13 TeV proton–proton collision data from Run 2 of the Large Hadron Collider.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
