dc.description.abstractWe propose a "Higgs impostor" model for the 125 GeV boson, X, recently discovered at the LHC. It is a technipion, η_T, with I^G J^PC = 0^- 0^-+ expected in this mass region in low-scale technicolor. Its coupling to pairs of standard-model gauge bosons are dimension-five operators whose strengths are determined within the model. It is easy for the gluon fusion rate σ B (gg ⟶ η_T ⟶ 𝛾𝛾) to agree with the measured one, but η_T ⟶ ZZ^*,WW^* are greatly suppressed relative to the standard-model Higgs rates. This is a crucial test of our proposal. In this regard, we assess the most recent data on X decay modes, with a critical discussion of X ⟶ ZZ^* ⟶ 4𝓁. In our model the η_T mixes almost completely with the isovector 𝜋^0_T, giving two similar states, η_L at 125 Gev and η_H higher, possibly in the range 170--190 Gev. Important consequences of this mixing are (1) the only associated production of η_L is via 𝘱T ⟶ Wη_L, and this could be sizable; (2) η_H may soon be accessible in gg ⟶ η_H ⟶ 𝛾𝛾; and (3) LSTC phenomenology at the LHC is substantially modified.en_US

We critically examine the crucial ZZ* -> 4l data and argue that it does not justify identifying this boson as a Higgs. In addition, several minor corrections have been madeen_US
