The Neutrino: A Word Written in Blank Letters

Abstract

This article presents the neutrino’s complete dossier within ΨD, a non-mainstream framework reading particle quantities from discrete codes built from {2, 3, ln2, π}; the glossary and claim-status labels are in Sections 1.1–1.2. The neutrino is the roster’s only moving word, written in blank letters: its three codon digits are zero, the one filled digit the half turn (J = ½); neutrality, colorlessness, and the weak-gate-only reading follow. It is the mirror’s only fixed fermion code; the Majorana ruling descends. The emptiest word is the lightest: the direct mass bound maps to the top address, k > 289. Three neutrinos are three stops of one codon (family shift 2π/D); the directed cycle yields the zeroth words and the reverse-step word sin²θ₁₃ = e^(−π)/2 = 0.0216 (0.76σ). The unitarity anchor gives sin²θ₁₂ = 0.3186 (0.97σ) and locks θ₂₃ to δ_KM (1.5σ). The blank base (m₁ = 0) with the measured mass-squared differences predicts Σm_ν = 0.059 eV; cosmology cuts it both ways. The effective masses m_β ≈ 8.8 meV and m_ββ ≈ 1.6–3.8 meV sit an order below sensitivity (5.2). The address mirror x_ν + x_R = 2x_e narrows the empty collar’s window to the TeV class. The empty slot’s (ν_R) search addresses are tabulated with honest limits; in normal ordering full exclusion stays unreachable (m_ββ → 0). Literature overlaps (TM1, type-I seesaw) and open items are labeled by name; no coefficient was chosen post hoc; the lookelsewhere record is in Section 6.1.
