Abstract

The status of the experiment on the precise τ lepton mass measurement running at the VEPP-4M collider with the KEDR detector is reported. The mass value is evaluated from the τ + τ − cross section behavior around the production threshold. The preliminary result based on 15.2 pb −1 of data is m τ = 1776.69 −0.19 +0.17 ± 0.15 MeV .
