Abstract

We discuss that conventional Technicolour dynamics can be revitalized within the Dark Technicolour paradigm by invoking the Extended Most Attractive Channel hypothesis. In this framework, Standard Model fermions acquire masses via multifermion chiral condensates arising from new strong dynamics. The model incorporates three confining gauge sectors, Technicolour, Dark Technicolour, and an intermediate QCD-like sector, linked through extended gauge symmetries. The Extended Most Attractive Channel hypothesis reveals a hierarchical structure of condensates, where channels with higher net chirality become increasingly attractive. At low energies, the Dark Technicolour paradigm naturally reduces to the Froggatt-Nielsen or Standard Hierarchical Vacuum Expectation Value model, governed by residual discrete symmetries, offering a compelling resolution to the Standard Model Flavor Problem.
