Description
New long-lived particles (LLPs) are a class of particles that are generically predicted in various theoretical extensions of the Standard Model (SM) such as those with Dark Matter candidates. The LHC has a detailed programme to search for LLPs produced at energies at the electroweak scale and above, which has mostly been focused on ‘prompt’ decays within the LHC experiments. In contrast, the ANUBIS experiment has been proposed to exploit the available space in the ATLAS cavern to search for LLPs with decay lengths of O(10m) and above. To do so the ceiling and bottom of the service shafts above the ATLAS experiment will be instrumented with tracking stations. This talk will present the latest results of ANUBIS’ sensitivity to a variety of new physics models that predict LLP signatures, focusing on Heavy Neutral Leptons, using the SET-ANUBIS framework. This newly developed framework aims to provide an easy way to simulate and compare a variety of models at ANUBIS.
