Abstract

We interpret the recent discovery by MkII at the SLC that the number of massless neutrino generations is 3 to mean that the family symmetry is indeedSU3 so that our «low energy» symmetry group isSU2L×U1×SU3 c ×SU3 f where low now means small compared to the Planck mass A possible model with a large topquark mass is exhibited The model is made complete by analogy with the originalSU3flavor model of GellMann In fact if the latter analogy is pursued literally it leads tomt≅658 −85 +397 GeV Such a value is currently still viable
