Abstract
We present a measurement of the cross section for production times the branching fraction to leptons, , in collisions at in the channel in which one decays into , and the other into or . The data sample corresponds to an integrated luminosity of collected with the D0 detector at the Fermilab Tevatron collider. The final sample contains 2008 candidate events with an estimated background of 55%. From this we obtain , in agreement with the standard model prediction.
