- Summary
- Using data taken by the Mark II detector at PEP, the decays of B hadrons are tagged by identifying leptons at high transverse momentum. By means of a precision inner drift chamber, the impact parameters of these leptons are measured with respect to the B production point. From this impact parameter distribution, the B hadron lifetime is found to be 0.98 +- 0.12 +- 0.13 ps. This measurement can be used to place constraints models of quark mixing. 11 refs., 2 figs., 2 tabs.
