Uc. Pandey et S. Dev, MAJORANA NEUTRINO TRANSITION MAGNETIC-MOMENT IN A SUPERSTRING INSPIRED MINIMAL E-6 MODEL, Journal of the Physical Society of Japan, 66(7), 1997, pp. 1853-1855
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' s
ymmetries prevalent in most other models for large neutrino magnetic m
oments.
