Abstract
We have measured the lifetimes of hadronically produced charged and neutralD mesons using silicon microstrip detectors and an active silicon target in the NA32 spectrometer at the CERN SPS. We obtainτ D± = (10.9± 1.91.5 )·10−13s andτ (−)10 D = (4.2±0.5)·10−13s based on 59 and 90 fully reconstructed decays respectively, giving a ratioτ D±/τ (−)10 D of 2.6 ±0.5.
