“…For our sample choice of parameters this is ∼ 10 −14 , giving a branching ratio 5×10 −13 , well below the observational bound BR < 3 × 10 −6 [23]. However, for other choices one can obtain much higher values, even larger than the present limit.…”

We present a simple model for neutrino dark matter in which neutrino masses arise radiatively and the solar neutrino data are explained via the MSW effect. The dark matter scale arises at the one-loop level while the MSW scale arises only in two-loops. The model is compatible with all observational facts and allows observable ν e ν τ or ν µ ν τ oscillation rates in the laboratory if the limits from primordial big bang nucleosynthesis (BBN) are taken conservatively. In addition, it can be probed by searching for muon number violating processes such as µ → e + γ, and µ → 3e. These rates can well lie within the sensitivities of present experiments. Finally, if we ignore BBN limits we can have also a common explanation for the atmospheric neutrino deficit via ν µ oscillations to a sterile neutrino ν S with maximal mixing and 10 −2 − 10 −3 eV 2 .

“…Current bounds on BR(µ → eχ) and on BR(τ → µχ) of 2.10 −6 and 7.10 −6 [3] respectively are sufficient to constrain ν µ and ν τ lifetimes to be longer than 10 29 s and 10 20 s. The only possibility for fast invisible decays of neutrinos seems to lie with majoron models. There are two classes of models; the I=1 Gelmini-Roncadelli [4] majoron and the I=0 Chikasige-Mohapatra-Peccei [5] majoron.…”

Abstract. It is shown that explanations of atmospheric neutrino anomaly other than ν µ − ν τ oscillations (e.g. decay, decoherence and ν µ − ν τ − ν KK mixing) can be tested at future facilities. Stringent tests of CPT invariance in neutrino oscillations can also be performed. I INTRODUCTIONIn this talk I would like to (a) review some non-oscillatory explanations for the atmospheric neutrino data, and how they can be distinguished from the conventional oscillatory explanations in future neutrino experiments; and (b) describe briefly the strong limits that can be placed on CPT violation both from existing data as well as future experiments especially at neutrino factories. II NEUTRINO DECAY, DECOHERENCE AND EXTRA DIMENSIONSDecay If neutrinos do have masses and mixings; then in general, in addition to oscillating, the heavier neutrinos will decay to lighter ones via flavor changing processes. The only questions are (a) whether the lifetimes are short enough to be interesting and (b) what are the dominant decay modes. To be specific, let us assume that neutrino masses are at most of order eV [1].For eV neutrinos, the only radiative mode possible is ν i → ν j + γ. From the existing bounds on neutrino magnetic moments, indirect (but model independent) bounds on the decay rates for this mode can be derived: 10 −11 s −1 , 10 −17 s −1 and 10 −19 s −1 for ν τ , ν µ and ν e respectively[1].

“…There are experimental upper bounds on the coefficient of each vertex, (except of course the SM (V − A) × (V − A) vertex, for which there is a lower bound). The coefficient g S RR of the vertex 2 √ 2G F (ēP L ν)(νP R µ) is required to be less than .066 [51].…”

Bileptons: present limits and future prospects

We define bileptons to be bosons coupling to a pair of leptons and construct the most general dimension four lagrangian involving scalar and vector bileptons. We concentrate on fields with lepton number 2, and derive model independent bounds on their masses and couplings from low-energy data. In addition, we study their signals in high energy experiments and forecast the discovery potential of future colliders.
