“…[25]. Diagram T1-i has been discussed in the context of the supersymmetric version of the dark doublet model [31,69]. Since these have been extensively studied in the literature (although not all possible versions, see the Appendix), we will not discuss them in greater detail.…”

We perform a systematic study of the d = 5 Weinberg operator at the one-loop level. We identify three different categories of neutrino mass generation: (1) finite irreducible diagrams; (2) finite extensions of the usual seesaw mechanisms at one-loop and (3) divergent loop realizations of the seesaws. All radiative one-loop neutrino mass models must fall into one of these classes. Case (1) gives the leading contribution to neutrino mass naturally and a classic example of this class is the Zee model. We demonstrate that in order to prevent that a tree level contribution dominates in case (2), Majorana fermions running in the loop and an additional Z 2 symmetry are needed for a genuinely leading one-loop contribution. In the type-II loop extensions, the Yukawa coupling will be generated at one loop, whereas the type-I/III extensions can be interpreted as loop-induced inverse or linear seesaw mechanisms. For the divergent diagrams in category (3), the tree level contribution cannot be avoided and is in fact needed as counter term to absorb the divergence.

“…The phenomenology of this model is extremely rich, covering areas such as dark matter, neutrino masses, collider searches, and lepton flavour violation, and it has been extensively studied in the literature -see e.g. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Fermionic WIMPs and vacuum stability in the scotogenic model

et al. 2016

View full text Add to dashboard Cite

We demonstrate that the condition of vacuum stability severely restricts scenarios with fermionic WIMP dark matter in the scotogenic model. The sizable Yukawa couplings that are required to satisfy the dark matter constraint via thermal freeze-out in these scenarios tend to destabilise the vacuum at scales below that of the heaviest singlet fermion, rendering the model inconsistent from a theoretical point of view. By means of a scan over the parameter space, we study the impact of these renormalisation group effects on the viable regions of this model. Our analysis shows that a fraction of more than 90% of the points compatible with all known experimental constraints -including neutrino masses, the dark matter density, and lepton flavour violation -is actually inconsistent.

“…Here we aim to employ non-Abelian discrete symmetries with a slightly different point of view, namely we want to emphasize the possibility of additional phenomenology of non-Abelian flavor symmetries at the electroweak scale [3,5,15,18,[27][28][29][30][31][32][33][34][35][36]. Thus, instead of only concentrating on predicting mixing angles, we have additional tests of models at our disposal, e.g.…”

Higgs →μτ in Abelian and non-Abelian flavor symmetry models

et al. 2015

View full text Add to dashboard Cite

We study lepton flavor violating Higgs decays in two models, with the recently found hint for Higgs → μτ at CMS as a benchmark value for the branching ratio. The first model uses the discrete flavor symmetry group A 4 , broken at the electroweak scale, while the second is renormalizable and based on the Abelian gauge group L μ − L τ . Within the models we find characteristic predictions for other non-standard Higgs decay modes, charged lepton flavor violating decays and correlations of the branching ratios with neutrino oscillation parameters.
