Triple

Target class: lepton number generation mechanism
Context triple: [Leptogenesis, instanceOf, lepton number generation mechanism]

• A. anomaly cancellation mechanism
  An anomaly cancellation mechanism is a theoretical consistency requirement in quantum field theories whereby contributions from different fields or symmetries are arranged to exactly cancel gauge or gravitational anomalies, ensuring the preservation of gauge invariance and unitarity.
• B. electroweak process
  An electroweak process is a physical interaction governed by the unified electromagnetic and weak forces, typically involving the exchange of W, Z, or photon gauge bosons between elementary particles.
• C. weak isospin symmetry
  Weak isospin symmetry is an SU(2) gauge symmetry of the Standard Model that organizes left-handed fermions into doublets and governs their interactions via the W and Z bosons in the electroweak sector.
• D. neutrino physics process chosen
  A neutrino physics process is an interaction or transformation involving neutrinos—such as their production, propagation, oscillation, or detection—governed by the weak force and described within the framework of particle physics.
• E. parameter of the Standard Model
  A parameter of the Standard Model is a fundamental numerical input—such as a particle mass, coupling constant, or mixing angle—whose value is not predicted by the theory itself but must be determined experimentally to fully specify its physical predictions.
• F. None of above.
