Dobrescu has recently proposed a renormalizable model whose infrared dynamics can plausibly generate the Standard Model's spectrum. The candidate IR theory is a type-II 2HDM with composite quarks and leptons. To generate an acceptable flavour structure, the model requires at least two additional heavy scalars which generate flavour-violating processes that are then correlated with the CKM matrix. Furthermore the theory predicts a relatively slow proton decay rate, such that flavour physics has the opportunity to be competitive. I will focus on how the quark and lepton mass matrices arrise in this theory, how to connect it to flavour physics observables, and phenomenological prospects.
