摘要:
Majorana neutrino transition magnetic moments [MNTM] in a superstring inspired E-6 model are investigated. The additional fermions in the 27-plet of E-6 are shown to lead to a large enough MNTM for a reasonable choice of Yukawa couplings without imposing the additional 'exotic' symmetries prevalent in most other models for large neutrino magnetic moments.
