Abstract

Using a high-statistics sample of -pair events collected with the CLEO detector operating at the Cornell Electron Storage Ring at s =10.5 GeV, we have measured =(3.250.140.18) ×10-13 sec. The experimental method for determining the lifetime includes both the reconstruction of decay vertices and the impact-parameter technique.
