How this entity was disambiguated
This entity first appeared as the object of triple T478292 — 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: quantum field theory Context triple: [Feynman rules, field, quantum field theory]
-
A.
Euclidean quantum field theory
Euclidean quantum field theory is a formulation of quantum field theory in imaginary (Euclidean) time that enables rigorous mathematical treatment and path-integral representations closely connected to statistical mechanics.
-
B.
quantum electrodynamics
Quantum electrodynamics is the quantum field theory that describes how light and matter interact through the exchange of photons, forming the foundation of our understanding of electromagnetic forces at the subatomic level.
-
C.
quantum chromodynamics
Quantum chromodynamics is the quantum field theory that describes the strong nuclear force binding quarks and gluons inside hadrons such as protons and neutrons.
-
D.
Feynman path integral
The Feynman path integral is a formulation of quantum mechanics in which a particle’s behavior is described as a sum over all possible paths it can take, each weighted by a phase factor derived from the classical action.
-
E.
Feynman diagrams
Feynman diagrams are graphical representations used in quantum field theory to visualize and calculate particle interactions and processes.
- 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: quantum field theory Description of subject: Quantum field theory is the theoretical framework in physics that combines quantum mechanics and special relativity to describe particles as excitations of underlying fields and governs their interactions.
