Long-lived particles are predicted by many extensions of the Standard Model and
have been gaining interest in recent years. The ANUBIS detector is a competitive
proposal that substantially extends the sensitivity in lifetime by instrumenting
the existing service shafts above the ATLAS or CMS experiments with tracking
stations. For scenarios with electrically neutral long-lived particles with m > 1 GeV,
the lifetime reach is increased by 2-3 orders of magnitude compared to
currently operating and approved future experiments at the LHC. In the talk, I
will discuss the physics case for ANUBIS, review its detector technology, and
outline the next steps for building and operating a prototype ANUBIS detector in
2022 at the LHC.
