Abstract

We report measurements of the lifetimes of the D0, D+, and Ds+ (F+) mesons produced in e+e- collisions at a center-of-mass energy of 29 GeV. The decay vertex distributions in the processes D0K-, D+K-, and Ds+' were made using a vertex chamber installed in the High Resolution Spectrometer at the SLAC storage ring PEP. The measured lifetimes are & =(4.4±1.0±0.6) ×10-13 s, &=(9.2-1.3+1.7± 1.6)×10-13 s, and &=(3.1-2.0+2.4±0.5) ×10-13 s. In addition the lifetime of the B0 meson is determined assuming that only the B0 and not the B- decays to a D*+ meson. The B0 is not directly observed. The lifetime & is estimated indirectly to be (8.2-3.7+5.7±2.7) ×10-13 s.
