# Measurement of the [Formula Presented] and [Formula Presented] meson lifetimes using semileptonic decays

Journal Article

The lifetimes of the [Formula Presented] and [Formula Presented] mesons are measured using the partially reconstructed semileptonic decays [Formula Presented] where [Formula Presented] is either a [Formula Presented] or [Formula Presented] meson. The data were collected by the CDF detector at the Fermilab Tevatron collider during 1992–1995 and correspond to about [Formula Presented] of [Formula Presented] collisions at [Formula Presented] We measure decay lengths and extract the lifetimes to be [Formula Presented] ps and [Formula Presented] and the ratio of the lifetimes to be [Formula Presented] where the first uncertainties are statistical and the second are systematic. © 1998 The American Physical Society.
