Description
The Standard Model (SM), despite its successes, is known to have several major limitations, such as the inability to describe Dark Matter, which has been astronomically observed. These limitations have led to the development of a variety of Beyond the Standard Model (BSM) theories to resolve them, which can often give rise to Long-Lived Particles (LLPs). LLPs provide a valuable probe of BSM models, so the ANUBIS experiment was proposed as a dedicated LLP experiment transverse to the beamline at ATLAS to explore regions of parameter space not previously covered by any existing experiments. A prototype detector, proANUBIS, operated for two years in the ATLAS cavern, accumulating around 176.3 fb^-1 of pp data. The first study of the proANUBIS dataset focused on searching slow muons, β>0.8, by synchronisation with ATLAS data as an excellent proof of concept of the possibilities of a symbiotic relationship between ANUBIS and ATLAS. Additionally, updated sensitivities to Heavy Neutral Leptons (HNLs) and Axion-Like Particles (ALPs), as well as the ongoing development of the SET-ANUBIS Sensitivity studies framework, are highlighted.
