Tau Neutrino Structure

CPP Tau Neutrino Model: Heaviest Neutrino

• Structure: eDP pair with configuration associated with tau lepton.
• Charge: Neutral - balanced +eCP and -eCP.
• Mass: Heaviest neutrino, upper bound ~18 MeV (still very light).
• Association: Produced with tau leptons in weak interactions.

The Last Neutrino Discovered

The tau neutrino was the last Standard Model fermion to be directly observed, detected at Fermilab's DONUT experiment in 2000. Its existence was inferred from tau lepton decays long before direct detection. In CPP, the ντ has the most complex internal eDP configuration of the neutrinos, correlating with its association to the heavy tau lepton. It participates in tau decay: τ⁻ → μ⁻ + ν̄μ + ντ or τ⁻ → e⁻ + ν̄e + ντ.
