The forward-backward asymmetry $A_{FB}^{t\bar t}$ in top quark production atthe Tevatron has been observed to be anomalously large by both CDF and D0. Ithas been suggested that a model with a $W'$ coupling to $td$ and $ub$ mightexplain this anomaly, and other anomalies in $B$ mesons. Single-top-quarkproduction in this model is large, and arguably in conflict with Tevatronmeasurements. However the model might still be viable if $A_{FB}^{t\bar t}$ issomewhat smaller than its current measured central value. We show that evenwith smaller couplings, the model can be discovered (or strongly excluded) atthe LHC using the 2010 data sets. We find that a suitable charge-asymmetrymeasurement is a powerful tool that can be used to constrain this and othersources of anomalous single-top production, and perhaps other new high-energycharge-asymmetric processes.
