Wolfenstein Parameter A
Wolfenstein Parameter A: τ-value 0.825, observed 0.826, deviation -887~ppm.
Prediction
τ-Formula
A = 1 − (3/2) · ι_τ² ≈ 0.825
Derivation
The Wolfenstein parameter $A = |V_cb|/λ^2$ satisfies:
where the coefficient $32$ is the ratio $|gen|/|lobes| = 3/2$, counting the three generations over the two lobes of the lemniscate $$. The PDG 2024 value is $A = 0.826 ± 0.012$, giving a deviation of $-887$ ppm ($-0.09%$).
The appearance of the ratio $|gen|/lobes = 3/2$ is a recurring theme: it also governs the Koide formula correction (Book IV, IV.T143) and the muon–electron mass ratio exponent (Book IV, IV.T148). The two lobes of $$ are the topological units on which the generation structure is built.
