Abstract
Long-lived particles (LLPs) arise in several beyond the Standard Model (BSM) theories, and they provide striking (non-standard) signatures at colliders. Several LHC searches look for LLP models in a broad range of final states, and limits have been presented for specific BSM models. However, extrapolating such limits to other scenarios often proves to be a difficult task outside the experimental collaborations. This note discusses the recasting of three types of LLP signatures: displaced vertices, displaced leptons and heavy stable charged particles. Several conclusions are obtained from these recasting attempts and recommendations to the experimental collaborations are made.
