Abstract
We propose a one-loop neutrino mass model with several SU(2)L multiplet fermions and scalar fields in which the inert feature of a scalar to realize the one-loop neutrino mass can be achieved by the cancellation among Higgs couplings thanks to non-trivial terms in the Higgs potential and to present it in a simpler way. Then we discuss our typical cut-off scale by computing renormalization group equation for SU(2)L gauge coupling, lepton flavor violations, muon anomalous magnetic moment, possibility of dark matter candidate, neutrino mass matrix satisfying the neutrino oscillation data. Finally, we search for our allowed parameter region to satisfy all the constraints, and discuss a possibility of detecting new charged particles at the large hadron collider.

We propose a one-loop neutrino mass model with several SU (2)L multiplet fermions and scalar fields in which the inert feature of a scalar to realize the one-loop neutrino mass can be achieved by the cancellation among Higgs couplings thanks to non-trivial terms in the Higgs potential and to present it in a simpler way
The cut-off scale of a model is determined by the renormalization group equations (RGEs) of SU(2)L gauge coupling, and it implies that a theory can be within TeV scale, depending on the number of multiplet fields
We have proposed an one-loop neutrino mass model, introducing large multiplet fields under SU(2)L
Summary
Induced neutrino mass models are one of the promising candidates to realize tiny neutrino masses with natural parameter spaces at TeV scale and to provide a dark matter (DM) candidate, both of which cannot be explained within the standard model (SM). Using large SU(2)L multiplet fields, we would like to realize one-loop neutrino generation by inert scalar field without imposing additional symmetry such as Z2. In this case scalar quintet H5 is minimal choice for inert multiplet since scalar multiplet smaller than quintet develop a vacuum expectation value (VEV) by renormalizable interaction with SM Higgs field H like H4HHH for the quadruplet H4. Required inert feature can be realized not via a remnant symmetry but via cancellations among couplings in our scalar potential thanks to several non-trivial couplings [19] In such a case, generally DM could decay into the SM particles, but we can control some parameters so that we can evade its too short lifetime without requiring too small couplings. IV, we devote the summary of our results and the conclusion
