atmospheric neutrino anomaly

Target entity: atmospheric neutrino anomaly
Context triple: [IMB, observedPhenomenon, atmospheric neutrino anomaly]

• A. Super-Kamiokande neutrino observatory
  The Super-Kamiokande neutrino observatory is a large underground water Cherenkov detector in Japan designed to study neutrinos from the Sun, atmosphere, supernovae, and other cosmic sources, and to investigate neutrino oscillations and proton decay.
• B. Homestake solar neutrino experiment
  The Homestake solar neutrino experiment was a pioneering underground radiochemical detector in South Dakota that first measured solar neutrinos and revealed the solar neutrino problem, leading to major advances in neutrino physics.
• C. neutrino oscillation
  Neutrino oscillation is a quantum phenomenon in which neutrinos change from one flavor type to another as they travel, implying that they have mass and mix between flavor states.
• D. experiments at the Sudbury Neutrino Observatory
  Experiments at the Sudbury Neutrino Observatory were groundbreaking studies of solar neutrinos that provided key evidence for neutrino oscillations and the existence of neutrino mass.
• E. Kamiokande experiment
  The Kamiokande experiment was a pioneering Japanese neutrino observatory that provided key evidence for solar and atmospheric neutrinos, contributing to the discovery of neutrino oscillations.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
