Abstract

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 MZ′∼270GeV which decays into a W± and a charged Higgs at MH±∼ 150GeV. 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.
