Description
CODEX-b, the COmpact DEtector for EXotics at LHCb, is a proposed particle detector for exotic long-lived particles (LLPs). These LLPs are potential candidates for dark sector portals, and so the observation of LLPs could unlock unexplored physics scenarios. Planned for installation near LHC interaction point 8, CODEX-b leverages fast resistive plate chambers (RPCs) with excellent temporal and spatial resolution. CODEX-b is sensitive to a wide range of new physics scenarios due to near zero-background environment which can be achieved with a fully hermetic structure and active shielding. A proof-of-concept demonstrator, CODEX-beta, is under construction, with data taking planned for late 2024 and 2025. CODEX-beta serves as a crucial validation platform for background measurements, integration with LHCb readout, and assessment of tracking and mechanical support systems.
