Abstract
The sign-dip probability of the impact parameter in the measurement of the tau lifetime is studied. The probability of the impact parameter with the negative value is introduced into the formula to fit the tau lifetime in the L3 experiment. The systematic errors of the drift velo city and grid time calibration on the lifetime are also studied by usi ng the special designed L3 Time Expansion Chamber (TEC).
