Resumen:
The ratio of the B+ and B0 meson lifetimes was measured using data collected in 20022004 by the D0 experiment in Run II of the Fermilab Tevatron Collider. These mesons were reconstructed in B à m+nD*- X decays, which are dominated by B0 and B à m+nD0 X decays, which are dominated by B+. The ratio of lifetimes is measured to be t+/t0 = 1.080 ± 0.016 (stat) ± 0.014 (syst).
