“…We note in passing that the lightest right-handed neutrino can be a DM candidate in our scenario discussed in this section. The phenomenology of fermionic DM is quite similar to that in the Ma's model [10][11][12][13][14][15][16], and its detailed discussions have been presented in ref. [17].…”

“…Our model is an extension of the model proposed by Ma [10][11][12][13][14][15][16], where neutrino masses are generated at the one-loop level. In the Ma model, three right-handed neutrinos and an inert scalar doublet field are added to the standard model (SM).…”

“…After the Zee model, the Zee-Babu model [2][3][4][5][6][7] has also been proposed, where neutrino masses are explained at the two-loop level. In 2000's, radiative neutrino mass models have been extended so as to include a dark matter (DM) candidate by introducing an unbroken symmetry such as a discrete Z 2 symmetry known as; e.g., the models by Krauss-Nasri-Trodden [8,9] and by Ma [10][11][12][13][14][15][16][17]. After these models appeared, various kinds of extensions have been considered in the scenario based on the raditive neutrino mass generation such as models with the supersymmetry [18][19][20][21], the B-L symmetry [22][23][24][25][26][27][28][29], flavour symmetries [30][31][32][33][34] and the conformal symmetry [35,36].…”

We propose a one-loop induced radiative neutrino mass model with anomaly free flavour dependent gauge symmetry: µ minus τ symmetry U(1) µ−τ . A neutrino mass matrix satisfying current experimental data can be obtained by introducing a weak isospin singlet scalar boson that breaks U(1) µ−τ symmetry, an inert doublet scalar field, and three right-handed neutrinos in addition to the fields in the standard model. We find that a characteristic structure appears in the neutrino mass matrix: two-zero texture form which predicts three non-zero neutrino masses and three non-zero CP-phases from five well measured experimental inputs of two squared mass differences and three mixing angles. Furthermore, it is clarified that only the inverted mass hierarchy is allowed in our model. In a favored parameter set from the neutrino sector, the discrepancy in the muon anomalous magnetic moment between the experimental data and the the standard model prediction can be explained by the additional neutral gauge boson loop contribution with mass of order 100 MeV and new gauge coupling of order 10 −3 .

“…Combining Eqs. (13) and (14), the minimum of the scalar potential can be obtained through ∂V /∂v h = 0 and ∂V /∂v ∆ = 0, and the minimum conditions can be written as: Because we focus on the case of µ ∆ < 10 −2 GeV, i.e., v ∆ 1 GeV, when we neglect the small…”

When a small vacuum expectation value of Higgs triplet (v ∆ ) in the type-II seesaw model is required to explain neutrino oscillation data, a fine-tuning issue occurs on the mass-dimension lepton-number-violation (LNV) scalar coupling. Using the scotogenic approach, we investigate how a small LNV term is arisen through a radiative correction when an Z 2 -odd vector-like lepton (X) and an Z 2 -odd right-handed Majorana lepton (N ) are introduced to the type-II seesaw model.Due to the dark matter (DM) direct detection constraints, the available DM candidate is the righthanded Majorana particle, whose mass depends on and is close to the m X parameter. Combing the constraints from the DM measurements, the h → γγ decay, and the oblique T -parameter, it is found that the preferred range of v ∆ is approximately in the region of 10 −5 − 10 −4 GeV; the mass difference between the doubly and the singly charged Higgs is less than 50 GeV, and the influence on the h → Zγ is not significant. Using the constrained parameters, we analyze the decays of each Higgs triplet scalar in detail, including the possible three-body decays when the kinematic condition is allowed. It is found that with the exception of doubly charged Higgs, scalar mixing effects play an important role in the Higgs triplet two-body decays when the scalar masses are near-degenerate. In the non-degenerate mass region, the branching ratios of the Higgs triplet decays are dominated by the three-body decays.

“…The same statement is true for the type II and the type III. In 2HDM type I, vanishing quadratic divergence are possible due to negative scalar quartic couplings, but this solution is contradict to the condition of positivity of the Higgs potential [15,18,19], therefore we concentrate on the 2HDM Model type II .…”

With the aim of exploring the Higgs sector of the Two Higgs Doublet Model (2HDM), we have chosen the exact and soft Z2 symmetry breaking versions of the 2HDM with non-zero vacuum expectation values for both Higgs doublets (Mixed Model). We consider two SM-like scenarios: with 125 GeV h and 125 GeV H. We have applied the condition for cancellation of quadratic divergences in the type II 2HDM in order to derive masses of the heavy scalars. Solutions of two relevant conditions were found in the considered SM-like scenarios. After applying the current LHC data for the observed 125 GeV Higgs boson, the precision electroweak data test and lower limits on the mass of H + , the allowed region of parameters shrink strongly.

Vanishing Higgs one-loop quadratic divergence in the scotogenic model and beyond

Abstract: It is shown that the inherent quadratic divergence of the Higgs mass renormalization of the standard model may be avoided in the well-studied scotogenic model of radiative neutrino mass as well as other analogous extensions.
