-
A.
Brookhaven E821 experiment
chosen
The Brookhaven E821 experiment was a high-precision particle physics experiment at Brookhaven National Laboratory that measured the anomalous magnetic moment of the muon, providing an important test of the Standard Model.
-
B.
Fermilab fixed-target program
The Fermilab fixed-target program is a series of high-energy physics experiments in which accelerated particle beams are directed onto stationary targets to study fundamental particles and interactions.
-
C.
Wu experiment
The Wu experiment was a landmark 1956 nuclear physics experiment that demonstrated the violation of parity conservation in weak interactions, fundamentally reshaping our understanding of fundamental symmetries in nature.
-
D.
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.
-
E.
Brookhaven Linac Isotope Producer
The Brookhaven Linac Isotope Producer is a particle-accelerator-based facility at Brookhaven National Laboratory that generates medical and research isotopes for nuclear medicine and scientific applications.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
Provenance (3 batches)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
