Abstract

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