How this entity was disambiguated
This entity first appeared as the object of triple T2208633 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: neutrino oscillation Context triple: [muon neutrino, participatesIn, neutrino oscillation]
-
A.
neutrino hypothesis
The neutrino hypothesis is Wolfgang Pauli’s 1930 proposal of a neutral, nearly massless particle to explain missing energy and momentum in beta decay, laying the groundwork for the discovery of the neutrino.
-
B.
tau neutrino
The tau neutrino is a fundamental, electrically neutral lepton associated with the tau particle, interacting only via the weak force and gravity and playing a key role in neutrino oscillations.
-
C.
muon neutrino
The muon neutrino is a fundamental, electrically neutral lepton in the Standard Model associated with the muon, interacting only via the weak force and gravity.
-
D.
MINOS experiment
The MINOS experiment is a long-baseline neutrino oscillation project that studied how neutrinos change type as they travel from Fermilab to a distant underground detector.
-
E.
Kobayashi–Maskawa theory
The Kobayashi–Maskawa theory is a fundamental framework in particle physics that explains CP violation in the Standard Model through a three-generation quark mixing matrix (the CKM matrix).
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: neutrino oscillation Description of subject: 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.
