| Popis: | The CDF collaboration recently presented evidence for an excess in the dijet invariant mass distribution coming from events in a W+2j exclusive sample. Here we show that this excess can be explained by the s-channel production of a weakly coupled Higgsophilic Z' near M_Z' ~ 270 GeV which decays into a W^\pm and a charged Higgs at M_{H^\pm} ~ 150 GeV. While the simplest implementations of a general leptophobic Z' model quickly run into tensions with electroweak observables, a more specific Higgsophilic model evades these constraints without resorting to any fine-tuning. We discuss the distinctive features of this model, focusing on its particular signatures at the Tevatron. Comment: 10 pages, 10 figures. Published version.
