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: unitarity triangle | Statement: [Kobayashi–Maskawa paper on CP violation (1973), relatedConcept, unitarity triangle]

Target entity: unitarity triangle
Context triple: [Kobayashi–Maskawa paper on CP violation (1973), relatedConcept, unitarity triangle]

• A. unitarity triangle chosen
  The unitarity triangle is a geometric representation in the complex plane of quark mixing and CP violation in the Standard Model, derived from the unitarity of the CKM matrix.
• B. 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.
• 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. 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).
• E. Weinberg angle
  The Weinberg angle, also known as the weak mixing angle, is a fundamental parameter in the electroweak theory that quantifies the mixing of electromagnetic and weak forces and determines the relative strengths of their interactions.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
