3717por Terranova, F“…MONOLITH is a proposed massive (34 kton) magnetized tracking calorimeter at the Gran Sasso laboratory in Italy, optimized for the detection of high energy atmospheric muon neutrinos. The main goal is to establish (or reject) the neutrino oscillation hypothesis through an explicit observation of the full first oscillation swing. …”
