How this entity was disambiguated
This entity first appeared as the object of triple T1096014 — 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.

-
A.
W boson
The W boson is a massive elementary particle that mediates the weak nuclear force and is responsible for processes like beta decay in the Standard Model of particle physics.
-
B.
Z′ bosons
Z′ bosons are hypothetical heavy neutral gauge bosons predicted by various extensions of the Standard Model, often associated with additional U(1) symmetries and searched for as resonances in high-energy collider experiments.
-
C.
Z boson
The Z boson is a neutral elementary particle that mediates the weak nuclear force and plays a central role in the electroweak theory of particle physics.
-
D.
Higgs boson
The Higgs boson is an elementary particle in the Standard Model whose associated field gives mass to other fundamental particles, confirming a key mechanism of particle physics.
-
E.
Salam–Weinberg model
The Salam–Weinberg model is the electroweak theory that unifies the electromagnetic and weak nuclear forces within the Standard Model of particle physics.
- 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: W′ bosons Description of subject: W′ bosons are hypothetical heavy counterparts of the Standard Model W bosons predicted by various extensions of particle physics, often searched for in high-energy collider experiments.
