  The CDF collaboration has reported a 4.1\sigma\ excess in their lepton,
missing energy, and dijets channel. This excess, which takes the form of an
approximately Gaussian peak centered at a dijet invariant mass of 147 GeV, has
provoked a great deal of experimental and theoretical interest. Although the
D\O\ collaboration has reported that they do not observe a signal consistent
with CDF, there is currently no widely accepted explanation for the discrepancy
between these two experiments. A resolution of this issue is of great
importance---not least because it may teach us lessons relevant for future
searches at the LHC---and it will clearly require additional information. In
this paper, we consider the ability of the Tevatron and LHC detectors to
observe evidence associated with the CDF excess in a variety of channels. We
also discuss the ability of selected kinematic distributions to distinguish
between Standard Model explanations of the observed excess and various new
physics scenarios.
