Opportunities with the SHiP experiment and the SPS Beam Dump Facility

• Richard Jacobsson (CERN)

Room: 100/-1-A900 - Auditorium Joliot Curie I will present the new opportunities offered by the proposed general-purpose intensity-frontier experimental facility BDF/SHiP that is design to operate in beam-dump mode in the existing SPS ECN3 experiment underground area. The proposal is part of the ongoing decision process at CERN that is focused on the beyond-LS3 physics program in ECN3, and that should come to conclusion by the end of 2023. The SHiP experiment aims to search for feebly interacting GeV-scale particles, and perform measurements in neutrino physics. BDF/SHiP complements the worldwide program of New Physics searches by exploring a large region of parameter space that cannot be addressed by other experiments, and which reaches several orders of magnitude below existing bounds by efficiently exploiting the currently available 4x10^19 protons per year at 400 GeV for up to 15 years. The SHiP experiment has generic sensitivity to decay and scattering signatures of models with feebly interacting particles, such as dark-sector mediators and light dark matter. In neutrino physics, BDF/SHiP can perform unprecedented measurements with tau neutrinos and neutrino-induced charm production. This proposal benefits from the extensive studies undertaken for the Technical Proposal submitted in 2015 and the subsequent Comprehensive Design Study (CDS) of BDF/SHiP located at a new beamline at the CERN SPS.
