Combined CDF and DØ Measurement of WZ and ZZ Production in b-tagged Channels with up to 9.5 fb-1 of Data
We measure the total WZ+ZZ cross section of 4.47±0.64 (stat)
–0.72 (syst) pb, which is
consistent with the standard model prediction and which corresponds to
a significance of 4.6 standard deviations above the background-only hypothesis.
This measurement is performed in the same data samples and
with the same event selection requirements and multivariate analysis training methods as those used by the
searches, considering the WZ and ZZ production processes
as signals instead of the Higgs boson signals. The WW process was considered a background,
as W boson decays contain b quarks only very rarely and never into a pair of b quarks.
The same note is available as CDF Note 10802 and DØ Note 6311, and FERMILAB-CONF-12-068-E
