“…Thus, in the limit λ → 0 the theory possesses the Z 2 symmetry {φ, F} → {−φ, −F}, making λ ≪ 1 technically natural. This symmetry is analogous to that invoked in both the KNT model [6] and the three-loop model with triplets [11]. In the limit that λ → 0 a stable particle emerges, which we return to in section 5.…”

We present a three-loop model of neutrino mass whose most-general Lagrangian possesses a softly-broken accidental Z 2 symmetry. In the limit that a single parameter vanishes, λ → 0, the Z 2 symmetry becomes exact and the model contains a stable dark-matter candidate. However, even for finite λ ≪ 1, long-lived dark matter is possible, giving a unified solution to the neutrino mass and dark matter problems that does not invoke a new symmetry. Taken purely as a neutrino mass model, the new physics can be at the TeV scale. When dark matter is incorporated, however, only a singlet scalar can remain this light, though the dark matter can be tested in direct-detection experiments.

Abstract:We describe a hybrid model in which the light neutrino mass matrix receives both tree-level seesaw and loop-induced contributions. An additional U(1) gauge symmetry is used to stabilize the lightest right-handed neutrino as the Dark Matter candidate. After fitting the experimental neutrino data, we analyze and correlate the phenomenological consequences of the model, namely its impact on electroweak precision measurements, the Dark Matter relic abundance, lepton flavour violating rare decays and neutrinoless double beta decay. We find that natural realizations of the model characterized by large Yukawa couplings are compatible with and close to the current experimental limits.

The problem of the dark matter in the universe is reviewed. A short history of the subject is given, and several of the most obvious particle candidates for dark matter are identified. Particular focus is given to weakly interacting, massive particles (WIMPs) of which the lightest supersymmetric particle is an interesting special case and a useful template. The three detection methods: in particle accelerators, by direct detections of scattering in terrestrial detectors, and indirect detection of products from dark matter particle annihilation in the galactic halo, are discussed and their complementarity is explained. Direct detection experiments have revealed some possible indications of a dark matter signal, but the situation is quite confusing at the moment. Very recently, also indirect detection has entered a sensitivity region where some particle candidates could be detectable. Indeed, also here there are some (presently non‐conclusive) indications of possible dark matter signals, like an interesting structure at 130 GeV γ‐ray energy found in publicly available data from the Fermi‐LAT space detector. The future of the field will depend on whether WIMPs are indeed the dark matter, something that may realistically be probed in the next few years. If this exciting scenario turns out to be true, we can expect a host of other, complementary experiments in the coming decade. If it is not true, the time scale and methods for detection will be much more uncertain.
