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: Gell-Mann–Nishijima formula | Statement: [Murray Gell-Mann, knownFor, Gell-Mann–Nishijima formula]

Target entity: Gell-Mann–Nishijima formula
Context triple: [Murray Gell-Mann, knownFor, Gell-Mann–Nishijima formula]

• A. Feynman–Hellmann theorem
  The Feynman–Hellmann theorem is a result in quantum mechanics that relates the derivative of an energy eigenvalue with respect to a parameter in the Hamiltonian to the expectation value of the corresponding derivative of the Hamiltonian.
• B. Dirac equation
  The Dirac equation is a fundamental relativistic wave equation in quantum mechanics that describes spin-½ particles such as electrons and predicts phenomena like antimatter.
• C. Noether's theorem
  Noether's theorem is a fundamental result in theoretical physics and mathematics that links continuous symmetries of a physical system to corresponding conservation laws, such as energy or momentum conservation.
• D. Murray Gell-Mann
  Murray Gell-Mann was an American physicist best known for developing the quark model of subatomic particles and receiving the 1969 Nobel Prize in Physics.
• E. 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.
• 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]"

Entity: Gell-Mann–Nishijima formula
Triple: [Murray Gell-Mann, knownFor, Gell-Mann–Nishijima formula]

The Gell-Mann–Nishijima formula is a key relation in particle physics that connects a particle’s electric charge to its isospin and hypercharge, helping classify hadrons within the quark model.
