Abstract

A universal parametrization for possible quark and lepton substructure is advocated in terms of quark and lepton form factors. It is emphasized that the lower bounds on compositeness scale, {Lambda}{sub c}, to be determined experimentally strongly depend on their definitions in composite models. From the recent HERA data, it is estimated to be {Lambda}{sub c} > 50 GeV, 0.4 TeV and 10 TeV, depending on the parametrizations with a single-pole form factor, a contact interaction and a logarithmic form factor, respectively. (author).
