Description
We present the status of two medium-baseline, kiloton-scale neutrino experiments to study neutrinos from LHC proton-proton collisions: SINE, a surface-based scintillator panel detector observing muon neutrinos from the CMS interaction point, and UNDINE, a water Cherenkov detector submerged in Lake Geneva observing all-flavor neutrinos from LHCb. SINE and UNDINE offer a cost-effective medium-baseline complement to the proposed short-baseline Forward Physics Facility. Using a Monte Carlo simulation, we estimate millions of neutrino interactions during the high-luminosity LHC era. These datasets can constrain neutrino cross sections, charm production in pp collisions, strangeness enhancement as a solution to the cosmic-ray muon puzzle, and heavy neutral leptons. We discuss new directions for expanding the physics program and report on progress toward prototype detectors.
