Description
Cosmology asks for modification of the Standard Model of particle physics (SM): one has to explain the baryon asymmetry of the Universe, the dark matter phenomenon, the flatness and homogeneity of the Universe, the origin of primordial matter perturbations.
The only direct evidence for incompleteness of the SM is neutrino oscillations,
which true extension of the SM also have to be capable of explaining. We suggest two simple examples of such extensions following two different guide lines: one avoiding new physical scales, another avoiding new interactions. Quite remarkable, the first model can be fully explored in particle physics experiments, the best place being B-factories.
