Abstract:

MONOLITH is a planned massive (34 kt) magnetized tracking calorimeter, optimized for the detection and study of oscillations of atmospheric muon neutrinos. Its main goal is to prove (or disprove) the neutrino oscillation hypothesis through an explicit (non)observation of the full first oscillation swing. The sensitivity range for this measurement () comfortably covers the region allowed by Super-Kamiokande. The experiment will also perform a precise and systematic-free measurement of . Other studies will address the hypothesis of mixing with a sterile neutrino, auxiliary measurements with the CERN to Gran Sasso neutrino beam, and cosmic ray muons in the multi-TeV range.
