SU(2)L septet scalar linking to a radiative neutrino model

We study a radiative neutrino model with a SU(2) septet scalar with hypercharge Y = 2 where active neutrino mass is induced at a one-loop level. Calculating a one-loop diagram, mass matrices for an active neutrino are derived. We also analyze lepton flavor violations, the anomalous magnetic moment of a muon, and the flavor-violating Higgs decay h -> mu tau. Then, sizable muon g - 2 and similar to 1% of BR(h -> mu tau) could be obtained in our setup. Furthermore, the collider signature of the septet is discussed, and we focus on the quadratically charged scalar at the LHC 14 TeV. We find that it could be discovered up to 1.5 TeV mass by searching multicharged lepton signal events.
