Rev. Mod. Phys., Vol. 84, No. 4, October–December 2012 The SM has been tested extensively over the last 40 years.
The only signiﬁcant deviation from its predictions is the
existence of neutrino mass. Ongoing studies of the SM are
being carried out by the Tevatron experiments, CDF, and D0.
This paper presents results of these tests and discusses prospects for the remainder of the Tevatron running and the
transition from the Tevatron to the LHC.
CDF and D0 presented a wide variety of results relating to
the EW sector. Among the results are observation of all SM
diboson processes involving W , Z, and , including for the
ﬁrst time WZ production, observation of EW production of
single-top quarks and the corresponding measurement of
jVtb j, the world’s best measurements of the top-quark and
W boson masses allowing improved indirect constraints on
the Higgs-boson mass, and ongoing searches for the Higgs
boson which have begun to exclude mass values outside of
the existing limits. In addition to testing the SM, some of
these are benchmark measurements eventually to be compared with corresponding results from the LHC. Others, such
as the top-quark and W boson masses, are likely to be legacy
measurements from the Tevatron.
With additional luminosity still to come for CDF and D0,
many of these measurements will signiﬁcantly improve
before the end of Run II at the Tevatron. This is an exciting
time in particle physics as the ﬁeld transitions from the era of
the Tevatron to an era of the LHC as the machine to probe
physics at the energy frontier.
ACKNOWLEDGMENTS The many beautiful experimental measurements summarized in this paper are the result of the work of thousands of
people from the Fermilab accelerator division, CDF and D0.
The authors wish to thank those involved in making these
possible. In addition, the authors thank Andrew Askew, Tom
Diehl, Reinhard Schwienhorst, and Junjie Zhu for useful
discussion and clariﬁcation.
