The masses of composite quarks and leptons as electromagnetic self energies

Abstract

In composite models of quarks, leptons and weak bosons quark and lepton masses vanish in the absence of electromagnetism. All quark and lepton masses are generated as electromagnetic effects whereby intermediate states with mass of order 1 TeV play an important role. The hierarchy pattern of lepton and quark masses follows, if one intermediate heavy state dominates the self energy diagram. In the absence of O(α 2) corrections the quarks of charge 2 3 are four times as heavy as the corresponding quarks of charge - 1 3 . These relations are violated by radiative corrections, giving rise simultaneously to the phenomenon of flavor mixing. The mass of the t quark is expected to be in the range between 20 and 28 GeV.
