Technicolor Explanation for the CDF Wjj Excess
Abstract
We propose that the 3.2σ excess at ∼150GeV in the dijet mass spectrum of W+jets reported by CDF is the technipion πT of low-scale technicolor. Its relatively large cross section is due to production of a narrow Wjj resonance, the technirho, which decays to WπT. We discuss ways to enhance and strengthen the technicolor hypothesis and suggest companion searches at the Tevatron and LHC.
