We present the result from a precision measurement of the mass of thelepton,, based onof data recorded at theresonance with theBABARdetector. Using a pseudomass endpoint method, we determine the mass to be. We also measure the mass difference between theand, and obtain (Mτ+-Mτ-)/MAVGτ=(-3.4±1.3(stat)±0.3(syst))×10-4, whereis the average value ofand.
