# LIB2-269 — Superseded Peirce-cylinder proposal for the tau mass

- class: RETIRED · review_state: PUBLISHED · house_tier: not yet assigned
- labels as printed: math_status None · attachment None · scorecard tier word none (PDF p.None)

## Statement

The archive proposed obtaining the tau mass from the muon mass through a power of a Peirce-cylinder ratio.

## Caution

Replacing the proposed physical formula does not exclude every cylinder relation or turn the measured tau anchor into a prediction.

## Primary source

Paper 2, §3.2, External tau role in the current chain, PDF p.36: "mτ is the external anchor; mµ follows from the algebraic ratio formula [A616, A618],"
