Description

We present a combined measurement of the cross section for the simultaneous production of two vector bosons (WZ,ZZ), where one of the bosons decays leptonically (W-->lv, Z-->ll or Z-->vv) and the other Z boson decays to bbar. The measurement uses the complete Run 2 dataset collected with the D0 detector in ppbar collisions at sqrt(s)=1.96 TeV, and combines the three leptonic decay modes mentioned above. This final state is a direct analog to SM Higgs searches in final states of leptons plus bottom quark pairs, and thus provides a crucial validation benchmark of the Higgs boson signal isolation techniques involved.
