Hybrid fourth generation: Technicolor with top-seesaw mechanism

We consider a model combining technicolor with the top-quark condensation. As a concrete model for technicolor, we use the minimal walking technicolor, and this will result in the appearance of a novel fourth generation whose leptons constitute a usual weak doublet while the QCD quarks are vectorlike singlets under the weak interactions. We carry out an analysis of the mass spectra and precision measurement constraints, and find the model viable. We contrast the model with present LHC data and discuss the future prospects.
