  A model describing the 4.1\sigma\ Wjj anomaly observed by the CDF experiment
at the Tevatron collider is introduced. It features new scalar particles which
are charged both under the SU(3)_C and the SU(2)_L gauge groups and which
couple to pairs of quarks. We introduce several identical replicas of the
scalar multiplets in order to leave an unbroken U(3)_Q x U(3)_U x U(3)_D flavor
symmetry to satisfy the constraints coming from flavor physics. We discuss the
LHC reach on the new scalar resonances both in the resonant production channel
(with the Wjj final state) and in the QCD pair production channel (with the 4j
final state).
