Abstract

We conjecture that there exists a scalar bound state for every pair of fundamental fermions at a UV (`composite') scale, Λvweak\Lambda\gg v_{\text{weak}}. This implies a large number of universally coupled, sub-critical Higgs doublets. All but the Standard Model Higgs are `dormant,' with large positive squared masses and each receives a small vacuum expectation values via mixing with the Standard Model Higgs. Universal couplings, modulo renormalization group running effects, flips the flavor problem into the masses and mixings of the Higgs system. Doublets associated with heavy fermion masses, b,c,τb,c, \tau likely lie in the multi-TeV range, but may be observable at the current LHC, or a high-luminosity and/or an energy-upgraded LHC. In the lepton sector we are lead to a Higgs seesaw for neutrino masses, and corollary processes of observable flavor violation. The observation of the first sequential doublet coupled to bˉb\bar{b}b with masses 3.5\lesssim 3.5 TeV would lend credence to the hypothesis.
