摘要：

I propose an explanation of the current discrepancy between the measured world average value and the theoretical value of the tau lepton lifetime. I argue that there exist common systematic errors in many of the experiments that use three-prong tau decays for the lifetime measurement. These systematic effects always shift the measurement towards longer lifetimes, and are caused by the small opening angle of three-prong tau decays and limited tracking chamber ability to resolve nearby hits. The theoretical tau life-time agrees well with the measured world average value from the one-prong tau decays.
