Seesaw neutrinos from the heterotic string. (English) Zbl 1228.81225
Summary: We study the possibility of realizing the neutrino seesaw mechanism in the \(E_8\times E_8\) heterotic string. In particular, we consider its \(Z_6\) orbifold compactifications leading to the supersymmetric Standard Model gauge group and matter content. We find that these models possess all the necessary ingredients for the seesaw mechanism, including the required Dirac-Yukawa couplings and large Majorana mass terms. We argue that this situation is quite common in heterotic orbifolds. In contrast with the conventional seesaw of grand unified theories (GUTs), no large GUT representations are needed to generate the Majorana mass terms. The total number of right-handed neutrinos can be very large, up to \(O(100)\).
