Description: We propose a model of Electroweak Symmetry Breaking (EWSB) that includes a technicolor sector and a Higgs-like boson. The model includes a bound state of technifermions held together by a new strong interaction, called the neutral technipion, which decays like a Standard Model (SM) higgs boson. By observing an excess in diphoton final states, the ATLAS and CMS collaborations have recently discovered a Higgs-like boson at 125 GeV. For a technipion of mass less than 200 GeV, we determine bounds on our model from the Large Hadron Collider (LHC) search for new scalar bosons decaying to photons. For a mass greater than 200 GeV, we consider the dominant decay mode to Z sigma, where sigma is a scalar boson of the model. An excess in this channel could provide evidence of the new pseudoscalar.
