Query: Third-family quark-lepton unification with a fundamental composite Higgs   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
$SU(4)\times SU(3)^\prime\times SU(2)_L\times U(1)_X$. 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.
