Název v původním jazyce

Supersymmetric standard model inflation in the Planck era

Popis výsledku v původním jazyce

We propose a cosmological inflationary scenario based on the supergravity-embedded Standard Model supplemented by the right-handed neutrinos. We show that with an appropriate Kähler potential the <i>L-H_u</i> direction gives rise to successfulinflation that is similar to the recently proposed gravitationally coupled Higgs inflation model but is free from the unitarity problem. The mass scale M_R of the right-handed neutrinos is subject to the seesaw relation and the present 2-? constraint from the WMAP7-BAO-<i>H</i>₀ data sets its lower bound M^R>~1 TeV. Generation of the baryon asymmetry is naturally implemented in this model. We expect within a few years new observational data from the Planck satellite clearly discriminates this model from other existing inflationary models arising from the same Lagrangian, and possibly yields stringent constraints on M_R.
