Description
We discuss extension of 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 that mixings among singly-charged bosons are negligible. Also lepton flavor violations are less constrained compared with the original model in such a scenario. Then we explore phenomenology of the model focusing on a doubly-charged boson physics at collider experiments such as the LHC and the ILC. This presentation is based on arXiv:1803.04795
