First direct observation of Muon antineutrino disappearance

This Letter reports the first direct observation of muon antineutrino disappearance. The MINOS experiment has taken data with an accelerator beam optimized for ν̄μ production, accumulating an exposure of 1.71×1020 protons on target. In the Far Detector, 97 charged current ν̄μ events are observed. Th...
