Multifield inflation

The aspects of modern cosmology related with new physics, predicted by particle theory are discussed here. The models of inflation, baryosynthesis, dark matter and dark energy, physics of very early Universe, cosmological nucleosynthesis, origin and properties of cosmic microwave background radiation, formation of large scale structure of the Universe, role and distribution of dark matter in the modern Universe are discussed here.

Question in chat at VIA lecture by D.Langlois on 26 september 2008
sergei rubin: (9/26/2008 16:53) Are there any observational limits on the mass of secondary fields?
sergei rubin: (16:54) the fields other than inflaton?
sergei rubin: (16:57) Vector fields also do exist.
belotsky k.: (17:01) In continuation of question of S.Rubin, is it possible to say something on physical properties of curvaton?
belotsky k.: (17:05) can't it be coupled to ordinary fileds?
