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: PMNS matrix | Statement: [neutrino oscillation, describedBy, PMNS matrix]

Target entity: PMNS matrix
Context triple: [neutrino oscillation, describedBy, PMNS matrix]

• A. Cabibbo–Kobayashi–Maskawa matrix
  The Cabibbo–Kobayashi–Maskawa matrix is a fundamental component of the Standard Model of particle physics that describes how quarks change flavor via the weak interaction and accounts for CP violation in the quark sector.
• B. 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).
• C. Cabibbo theory
  Cabibbo theory is a framework in particle physics that describes the mixing of down and strange quarks in weak interactions through a single mixing angle, laying groundwork later generalized by the CKM matrix.
• D. Gell-Mann matrices
  Gell-Mann matrices are a set of eight 3×3 traceless Hermitian matrices that serve as the generators of the SU(3) Lie algebra in quantum chromodynamics and other areas of particle physics.
• E. neutrino oscillation
  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.
• 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

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: PMNS matrix
Triple: [neutrino oscillation, describedBy, PMNS matrix]

The PMNS matrix is a unitary matrix in particle physics that encodes the mixing between neutrino flavor and mass eigenstates, governing the phenomenon of neutrino oscillations.
