OPERA faster-than-light neutrino anomaly (later refuted)

Target entity: OPERA faster-than-light neutrino anomaly (later refuted)
Context triple: [LNGS, notableEvent, OPERA faster-than-light neutrino anomaly (later refuted)]

• A. atmospheric neutrino anomaly
  The atmospheric neutrino anomaly is a historical discrepancy between predicted and observed atmospheric neutrino fluxes that provided key evidence for neutrino oscillations and nonzero neutrino mass.
• B. Daya Bay Reactor Neutrino Experiment
  The Daya Bay Reactor Neutrino Experiment is a major particle physics project in China that precisely measured the neutrino mixing angle θ₁₃ using antineutrinos from nuclear reactors, significantly advancing our understanding of neutrino oscillations.
• C. 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.
• D. Neutrino
  A neutrino is an extremely light, electrically neutral elementary particle that interacts only via the weak nuclear force and gravity, making it very difficult to detect.
• E. Cowan–Reines neutrino experiment
  The Cowan–Reines neutrino experiment was the first successful detection of neutrinos, providing direct experimental confirmation of their existence and validating key aspects of weak interaction theory.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: OPERA faster-than-light neutrino anomaly (later refuted)
Target entity description: The OPERA faster-than-light neutrino anomaly was a 2011 experimental result from the OPERA experiment that appeared to show neutrinos traveling faster than light, challenging special relativity, but was later traced to experimental errors and withdrawn.
