Probing the primordial helium abundance and the effective number of neutrino species with CMB Speaker(s): Toyoakazu Sekiguchi
Abstract: We point out that light scalar fields with symmetries generically generate non-Gaussianity in the density fluctuations. Our observation makes the presence of the non-Gaussianity ubiquitous. When the inflationary scale and the properties of the scalar fields satisfy a certain relation, the non-Gaussi... read more
