Abstract
Superficial non-unitarity of the quark-mixing matrix, which has been predicted to be momentum transfer dependent due to the possible substructure of quarks, is discussed in composite models of quarks and leptons. A precise measurement of the momentum transfer dependence of the branching ratios for inclusive hadronic decays of τ→vτ+ hadrons and for inclusive semi-leptonic decays of K, D, B and [Formula: see text] hadrons is proposed as one of the best experimental searches for a possible evidence of the substructure of quarks.
