Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: W′ bosons | Statement: [Drell–Yan processes, usedToSearchFor, W′ bosons]

Target entity: W′ bosons
Context triple: [Drell–Yan processes, usedToSearchFor, W′ bosons]

• 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.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. 
Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"
