MONOLITH: A MASSIVE MAGNETIZED DETECTOR FOR ATMOSPHERIC NEUTRINOS

The MONOLITH (Massive Observatory for Neutrino Oscillation or LImits on THeir existence) project is a proposal¹ for an experiment to be installed in the Gran Sasso underground laboratory to study atmospheric neutrino oscillations with a massive magnetized iron tracking calorimeter. The main purpose is to confirm the existence of atmospheric neutrino oscillations through the explicit observation of the first oscillation minimum in ν_μ disappearance. The MONOLITH detector has been designed in order to discriminate among different oscillation modes and to accurately measure the oscillation parameters in a range that completely covers the Super-Kamiokande allowed region. Other measurements include studies of matter effects, the NC up down ratio, the ratio, the study of cosmic ray muons in the multi-TeV energy region, and auxiliary measurements from the CERN to Gran Sasso neutrino beam.
