摘要：

Properties of leptons in the framework of the E8 × E'8 heterotic string compactified on three-generation Calabi-Yau manifolds are investigated. It is shown that the experimental smallness of neutrino masses, mv < O (10 eV), leads to restrictions on Yukawa couplings (and hence on the moduli of the three-generation manifolds) that naturally explains the smallness of me/mτ [i.e. me/mτ = O (10-3)]. Neutrino oscillations are calculated with ve,Ω {not left-right arrow} vτ being the dominant predicted oscillation. © 1990.
