1/Nsubcolour and Quark-Lepton Mass Hierarchies. II
K.-i. Matumoto, Koichi Yamawaki · Progress of Theoretical Physics · 1983
It is shown that a previously proposed scenario in which 1/Nsubcolour is the principal factor of quark-lepton mass hierarchies can be developed with a less restrictive assumption on the preon configurations of quarks-leptons.
