In light of the recent CDF report on the excess in the Wjj channel, we analyze (non)supersymmetric U(1)(B) x U(1)(l) model, interpreting the dijet peak as a leptophobic U(1)(B) gauge boson. If this excess is confirmed, it has an interesting implication for the baryonic cold dark matter (CDM) in the model: there should be light CDM with a few GeV mass, and direct detection cross section at the level of a few x 10(-2) pb.
