Abstract
We discuss the modified top quark condensation model proposed in Ref. 54. This construction was inspired by the top-seesaw scenario, in which the extra heavy fermion [Formula: see text] that may be paired with the top quark is added. Besides, this model incorporates the ideas of the little Higgs scenario, in which the 125 GeV scalar particle appears as a pseudo-Goldstone boson. This model admits (in addition to the 125 GeV scalar boson [Formula: see text]) the heavier scalar excitation [Formula: see text]. We consider the region of parameters, where its mass is [Formula: see text], the width of [Formula: see text] is [Formula: see text], while the mass of the heavy fermion is [Formula: see text]. We find that in this model the value of the cross-section [Formula: see text] for [Formula: see text] is essentially smaller than the present experimental upper bound. Besides, we find that for the chosen values of parameters there should exist the CP-even scalar boson with mass [Formula: see text] and very small width. In addition, the model predicts the existence of the extra neutral CP-even scalar boson and the charged scalar boson with masses of the order of 1 TeV.
