We construct a model of quark and lepton compositeness based on an SU(15) gauge interaction that confines chiral preons, which are also charged under the weakly coupled SU(4)PS×SU(2)L×SU(2)R gauge group. The breaking of the latter, down to the Standard Model group, is achieved by scalar SU(15) bound states at a scale in the 30–100 TeV range. The embedding of the QCD gauge group in SU(4)PS slows down the running of αs in the UV. We estimate the effects of the strongly coupled SU(15) dynamics on the running of the SU(4)PS×SU(2)L×SU(2)R gauge couplings, which likely remain perturbative beyond the compositeness scale of about 103–104 TeV, and even above a unification scale. A composite vectorlike lepton doublet acquires a mass in the TeV range probed at future colliders, and an extended Higgs sector arises from six-preon bound states.
