Abstract
We study the vacuum alignment of the top-mode pseudo-Nambu-Goldstone boson Higgs (TMpNGBH) model, which has recently been proposed as a variant of the top-quark condensate model in light of the 126 GeV Higgs boson discovered at the LHC. It is shown that the vacuum of the model, determined from the one-loop effective potential with all the explicit breaking effects included, realizes the electroweak symmetry breaking with the appropriate breaking scale. Phenomenologies of two characteristic particles in the TMpNGBH model, namely the $CP$-odd partner of the Higgs (${A}_{t}^{0}$) and the vectorlike partner of the top quark (${t}^{\ensuremath{'}}$), are also studied based on the newly identified vacuum.
