Zee-Babu type model with U(1)Lμ-Lτ gauge symmetry

We extend the Zee-Babu model, introducing local U(1)(L mu-L tau) symmetry with several singly charged bosons. We find a predictive neutrino mass texture in a simple hypothesis in which mixings among singly charged bosons are negligible. Also, lepton-flavor violations are less constrained compared with the original model. Then, we explore the testability of the model, focusing on doubly charged boson physics at the LHC and the International Linear Collider.
