Description

The scenario of SO(10) grand unified theory (GUT) proposed by one of the authors is extended to E6 unification. This gives realistic quark and lepton mass matrices. In the neutrino sector, the model reproduces the large mixing angle (LMA) MSW solution as well as the large mixing angle for the atmospheric neutrino anomaly. In this model, the right-handed down and the left-handed lepton of the first and second generations belong to a single multiplet 27. This causes natural suppression of the flavour changing neutral current (FCNC). (author)
