Description
The second MoEDAL Apparatus for Penetrating Particles (MAPP-2) is proposed for deployment at the High Luminosity LHC (HL-LHC) a large instrumented tunnel decay volume adjacent to IP8 with a volume of 1200m3. The detector utilizes large area scintillator panels with x-y WLS fibres readout by SiPMs arranged in a “Russian Doll configuration to measure the vertices of very Long-Lived Particles (LLPs) emanating from IP8. The detector incorporates a radiator layer to also allow the registration of photons in the final state. The sensitivity of MAPP-2 is complementary to other planned LLP detectors and the existing LHC general-purpose detectors. We shall discuss a few physics benchmarks to illustrate this sensitivity. The initial plans for deploying the MAPP-2 detector at the High Luminosity LHC (HL-LHC) were endorsed by the LHCC. A LoI, to be submitted to the Large Hadron Collider Committee, is under preparation.
