Measurement of the F Meson Lifetime.

A result on the first measurement of the lifetime of the F('(+OR-)) mesons produced in e('+)e('-) annihilations at 29 GeV is presented. These measurements have been made by using a high precision straw-type drift chamber along with the HRS detector at PEP. The data which. were analysed for these measurements corresponds to an integrated luminosity of 145 Pb('-1). The lifetime is measured to be. (DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI). based on 17 F('(+OR-)) Decays.
