An $SU(2)_L$ Septet Scalar Linking to Radiative Neutrino Model

Understand

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 active neutrino is derived.
• We also analyze lepton flavor violations, anomalous magnetic moment of muon and the flavor violating Higgs decay $h \to \mu \tau$.
• Then sizable muon $g-2$ and $\sim 1 \%$ of $BR(h \to \mu \tau)$ could be obtained in our set up.
