Inflation with nondynamic distortion to leading order in slow roll
Ali Hassan
We study inflation in metric-affine gravity. We write an action that contains all the second order algebraic distortion terms, and all first order distortion terms with a single co…

Inflation with the Gauss-Bonnet term in the Palatini formulation
Ali Hassan, Syksy Rasanen
We consider the Gauss-Bonnet term coupled to the inflaton in the Palatini formulation of gravity. Unlike in the metric formulation, the Gauss-Bonnet term is not always a total deri…

Inflation with the Chern-Simons term in the Palatini formulation
Ali Hassan, Syksy Rasanen
We consider the Chern--Simons term coupled to the inflaton in the Palatini formulation of general relativity. In contrast to the metric formulation, here the Chern--Simons term aff…
