Agut Masses
C. D. Froggatt, H. B. Nielsen
Abstract
From considerations of the number of matrix elements of different orders of magnitude in the quark and charged lepton mass matrices, we suggest that the underlying gauge group responsible for the spectrum should have several---actually of the order of 7 to 10---cross product factors. This is taken to support our AGUT gauge group SMG3 × U(1)f which, under certain simple conditions, is the maximal group transforming the known 45 Weyl quark-lepton fields into each other. We describe the AGUT fit to the charged fermion mass spectrum, and briefly discuss baryogenesis and the neutrino mass problem.
