  We discuss a test of the CDF dijet anomaly at the LHC. The recent observed
dijet mass peak at the CDF is well fitted by a new particle with a mass of
around 150 GeV, which decays into two jets. In this paper, we focus on only
$Wjj$ signal to avoid model dependence, and comprehensively study the LHC
discovery/exclusion reach. We found almost all the models are inconsistent with
the result of the LHC, unless only valence quarks contribute the new process.
We also discuss further prospects of the LHC search for this anomaly.
