Description
The High Luminosity LHC will be a tremendous opportunity to search for long lived particles (LLPs) from an extended hidden/dark sector, feebly connected to the known SM sector. Such LLP searches will require special detectors, placed far away from the proton-proton collision point and shielded against SM backgrounds. The CODEX-b detector, to be placed behind a thick shielding wall inside the LHCb cavern, around 25m from the LHCb interaction point, provides a novel solution. A crucial aspect is the detector technology that can provide good resolutions in both tracking (~mm) and timing (~100ps), and be inexpensive to cover large volumes. RPCs are very attractive for this purpose. This talk will give an overview of the CODEX-b proposal and describe the ongoing and future R&D towards its construction.
