Description
New long-lived particles (LLPs) are a class of particles that are generically predicted in various theoretical extensions of the Standard Model 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 outline the ANUBIS project, and its physics case before detailing the design, installation and commissioning of a completed prototype detector, proANUBIS, and a recent upgrade made to its trigger system. Additionally, an initial look at the 2024 commissioning data will be given, showing the ongoing progress and future plans for the experiment.
