Abstract

We plan to measure the mass of τ lepton near the threshold of its production with an accuracy 10^-4 or better in the experiment with the detector KEDR at the e⁺e^- collider VEPP-4M using the method of resonance depolarization for calibration of particle energy. The scenario of the experiment, the developed systems of polarimeters and the depolarizer are described. Some points regarding beam polarization and energy calibration accuracy are considered
