Covariant second-order perturbations in generalized two-field inflation
Eleftheria Tzavara, Shuntaro Mizuno, Bartjan van Tent
We examine the covariant properties of generalized models of two-field inflation, with non-canonical kinetic terms and a possibly non-trivial field metric. We demonstrate that kine…
Oscillatory features in the curvature power spectrum after a sudden turn of the inflationary trajectory
Xian Gao, David Langlois, Shuntaro Mizuno
In the context of two-field inflation characterized by a light direction and a heavy direction, we revisit the question of the impact of the massive modes on the power spectrum pro…
Orthogonal non-Gaussianity in DBI Galileon: prospect for Planck polarisation and post-Planck experiments
Kazuya Koyama, Guido Walter Pettinari, Shuntaro Mizuno +1
In this note, we study cosmic microwave background (CMB) constraints on primordial non-Gaussianity in DBI galileon models in which an induced gravity term is added to the Dirac-Bor…
