A minimal model for dark matter and neutrino masses — •Sonja Esch1, Carlos Yaguna2, and Michael Klasen1 — 1WWU Münster — 2MPI Heidelberg
We will present a minimal model for dark matter and neutrino masses. By adding one scalar and one fermionic doublet along with a scalar singlet and a fermion singlet to the Standard Model, it is possible to radiatively generate neutrino masses. A long with the new particles a Z2 symmetry is introduced, which stabilizes the new heavy particles, allowing the lightest one of them to be a dark matter candidate.
The coupling of the dark sector to the lepton sector, which generates the neutrino masses, on the one hand causes lepton flavour violation. On the other hand these new couplings can influence the dark matter relic density, while leaving the direct detection cross section nearly unaffected.
