    The Spectrum of Flavor Dissociation
    While the $2 \times 2$ matrix describes the original observation, the introduction of the third generation (the bottom and top quarks) demonstrated that the concept of flavor rotation is more pervasive than initially conceived. The single Cabibbo angle is now recognized as the $(1,2)$ element—or sometimes $(1,1)$ depending on indexing conventions—of the vastly more complex Cabibbo–Kobayashi–Maskawa (CKM) matrix.

    Connection to Generation Equivalence
    The Cabibbo angle establishes a hierarchy in the weak interaction: couplings involving the first two generations are dominant, while the coupling to the third generation (via the CKM matrix) is highly suppressed. The magnitude of the rotation angle $\theta_C$ is intrinsically linked to the difference in the vacuum expectation values (VEVs) of the Higgs field components associated with the first and second generations, …
