Vacuum Alignment of the Top-Mode Pseudo-Nambu-Goldstone Boson Higgs Model

摘要

We study the vacuum alignment of the top-mode pseudo-Nambu-Goldstone bosonHiggs (TMpNGBH) model, which has recently been proposed as a variant of the topquark condensate model in light of the 126 GeV Higgs boson discovered at theLHC. It is shown that the vacuum of the model, determined from the one-loopeffective potential with all the explicit breaking effects included, realizesthe electroweak symmetry breaking with the appropriate breaking scale.Phenomenologies of two characteristic particles in the TMpNGBH model, namelythe CP-odd partner of the Higgs and the vectorlike partner of the top quark arealso studied based on the newly identified vacuum.
