Mixed non-Gaussianity in multiple-DBI inflation
Jon Emery, Gianmassimo Tasinato, David Wands
We study a model of multiple-field DBI inflation leading to mixed form of primordial non-Gaussianity, including equilateral and local bispectrum shapes. We present a general formal…

Local non-Gaussianity from rapidly varying sound speeds
Jon Emery, Gianmassimo Tasinato, David Wands
We study the effect of non-trivial sound speeds on local-type non-Gaussianity during multiple-field inflation. To this end, we consider a model of multiple-field DBI and use the de…
