Modulation of the waterfall by a gauge field
David H. Lyth, Mindaugas Karciauskas
We present the first complete calculation of the curvature perturbation generated during the hybrid inflation waterfall, caused by the coupling of the waterfall field to a gauge fi…

Statistically anisotropic curvature perturbation generated during the waterfall
David H. Lyth, Mindaugas Karciauskas
If the waterfall field of hybrid inflation couples to a U(1) gauge field, the waterfall can generate a statistically anisotropic contribution to the curvature perturbation. We inve…

The hybrid inflation waterfall and the primordial curvature perturbation
David H. Lyth
Without demanding a specific form for the inflaton potential, we obtain an estimate of the contribution to the curvature perturbation generated during the linear era of the hybrid…
