摘要Augmenting the Standard Model by three right-handed neutrinos allows for an anomaly-free gauge group extension G(max) = U(1)(B-L) x U(1)(Le-L mu) x U(1)(L mu-L tau). While simple U(1) subgroups of G(max) have already been discussed in the context of approximate flavor symmetries, we show how two-zero textures in the right-handed neutrino Majorana mass matrix can be enforced by the flavor symmetry, which is spontaneously broken very economically by singlet scalars. These zeros lead to two vanishing minors in the low-energy neutrino mass matrix after the seesaw mechanism. This study may provide a new testing ground for a zero-texture approach: the different classes of two-zero textures with almost identical neutrino oscillation phenomenology can in principle be distinguished by their different Z' interactions at colliders.
