Sneutrino Inflation
arXiv:hep-ph/0403247 · doi:10.1016/j.nuclphysbps.2004.10.070
Abstract
The seesaw model of neutrinos might explain the size, age, flatness and near-homogeneity of the Universe via sneutrino inflation, as well as explaining the origin of matter via leptogenesis. The sneutrino inflation hypothesis makes specific, testable predictions for cosmic microwave background observables, which are compatible with the first release of data from WMAP, and for flavour-violating charged-lepton decays. In particular, mu -> e gamma should occur with a branching ratio very close to the present experimental upper limit, whilst tau -> mu gamma and e gamma should occur further below the present limits.
