Description
A future 10 TeV Muon Collider provides exciting opportunities to search for heavy long-lived particles (LLPs), but beam-induced backgrounds (BIB) from muon decays present a major challenge for detector performance and the reconstruction of these signatures. Previous detector studies have imposed standard hit-timing requirements to reduce BIB occupancy. However, such selections are optimized for Standard Model particles and can significantly reduce acceptance for slowly moving, charged LLPs whose delayed hits arrive outside nominal timing windows. As a benchmark scenario, long-lived staus in a gauge-mediated supersymmetry model are used to investigate the impact of loosened tracker timing requirements on signal reconstruction and physics sensitivity. By comparing multiple timing-window configurations and applying track-level and event-level selections to suppress BIB and Standard Model backgrounds, we demonstrate that extended tracker timing acceptance is essential for maximizing discovery potential for charged long-lived particles at a 10 TeV Muon Collider.
