Measurement of Exclusive B Lifetime in the modes B+ → J/&psi K+, B0 → J/&psi K*0, B0 → J/&psi K0s, B0s → J/&psi &phi and /\b → J/&psi /\, and measurement of the B+/B0, B0s/B0 and /\b/B0 lifetime ratios

This web page summarizes the results for the measurement of the above B hadron's lifetimes performed using the above exclusive J/&psi decay channels, based upon 1 fb-1 of data.
The results have been approved as of November 30, 2006.
This result supersedes the previous measurement performed with 195 pb-1, the previous measurement performed with 240 pb-1 and the previous measurement performed with 1fb-1.
