Description
Previous searches for BSM LLPs produced at the LHC have been hindered by a lack of tracking detectors existing at a significant distance from the interaction point. The ATLAS Experiment’s detectors only cover up to about 10 m from the LHC’s beam line, which causes the Experiment’s sensitivity to LLPs to drop-off significantly for particles with proper lifetimes in excess of O(10 ns). The ANUBIS project proposes addressing this issue by installing a new set of tracking detectors along the ceiling of the ATLAS Experiment’s cavern and/or within its service shaft. Studies show that these new detectors combined with ATLAS’ existing detectors would be sensitive to the decays of neutral BSM LLPs with ctau reaching up to 10^6 m; a significant improvement which could be realized at a relatively modest cost. This talk will discuss the proposed layouts of the ANUBIS project, their sensitivities to a representative model of BSM LLPs, and the ongoing work of constructing a prototype detector to measure the background rates in this new and exciting region of the ATLAS Experiment.
