Primordial formation hybrid inflation

We calculate the contribution to the curvature perturbation, that is generated while the waterfall field grows exponentially (which can occur only if the waterfall field mass is $m\gg H$). We consider...
Mutated hybrid inflation in $f(R,{\Box}R)$-gravity
Mutated hybrid inflation High Energy Physics

A new hybrid inflationary scenario in the context of $f(R,{\Box}R)$-gravity is proposed. Demanding the waterfall field to 'support the potential from below' [unlike the original proposal by Stewart i...
We discuss the hybrid inflation model where the inflaton field is nonminimally coupled to gravity.In the Jordan frame, the potential contains φ4 term as well as terms in the original hybrid inflation ...

Waterfall field in hybrid inflation and curvature perturbation

We study carefully the contribution of the waterfall field to the curvature perturbation at the end of hybrid inflation. In particular we clarify the parameter dependence analytically under reasonable...
