Abstract
The ratio of the and meson lifetimes was measured using data collected in 2002–2004 by the D0 experiment in Run II of the Fermilab Tevatron Collider. These mesons were reconstructed in decays, which are dominated by and decays, which are dominated by . The ratio of lifetimes is measured to be .
