We present a model for third-family quark-lepton unification at the TeV scale featuring a composite Higgs sector. The model is based on a variant of the Pati-Salam model, the so-called 4321 model, consisting of the gauge group SU(4) x SU(3)' x SU (2)(L) x U(1)(x). The spontaneous symmetry breaking to the SM gauge group is triggered dynamically by a QCD-like confining sector. The same strong dynamics also produces the Higgs as a pseudo Nambu-Goldstone boson, connecting the energy scales of both sectors. The model predicts a massive U-1 vector leptoquark coupled dominantly to the third generation, recently put forward as a possible solution to the B-meson anomalies. (C) 2020 The Authors.
