Symmetry Breaking Patterns in E6

  • Feza Gürsey
Part of the Lie Groups: History, Frontiers and Applications book series (LGR, volume 11)


The two possible ways of using the exceptional group E6 as a grand unified gauge model are discussed. Natural directions that occur in its breaking are exhibited through a generalization of a method employed by Michel and Radicati. The corresponding Higgs sector is analyzed both for elementary or composite Higgs scalars. The possible enlargement of the electroweak group from SU(2)W × u(l) to SU(2)W × SU’(2)W × u(l) is discussed in the two generations (topless) mode. The possibilities of neutron oscillations and neutrino masses are indicated in both topless and standard (t-quark containing) versions.
