摘要：

The neutrino mass problem is discussed in the context of the E6, SU(5) X U(1) and SU(4) X SO(4) models. It is found that the right handed neutrinos receive large Majorana masses radiatively, through a two loop diagram originally proposed by Witten for the SO(10) theory. Thus an effective see-saw mechanism becomes effective. The resulting left handed neutrino mass spectrum is discussed in detail in each model separately.
