Scientific paper

We demonstrate that there is no evidence of any Wjj excess or deficit within CDF data if a data-derived background estimation that includes single-top-quark production is used instead of a Monte Carlo estimate. Instead, when coupled with the CDF measurement of single-top-quark production, a more interesting anomaly exists within CDF data: namely, there are too many W+0 b-tag and W+2 b-tag events, and too few W+1 b-tag events. As we previously predicted, there is no significant evidence of any of these anomalies in the D0 data set.
