Keeping the relation between the Starobinsky model and no-scale supergravity ACTive

Journal of Cosmology and Astroparticle Physics
We introduce a modification of the Starobinsky model in the form of an additional cubic Ricci scalar curvature term ∼ αR 3, scaled by a dimensionless parameter α, with the resulting inflaton potential being the standard Starobinsky potential modified to ...

Old-minimal supergravity models of inflation

, 2013
A bstractWe study three types of the old-minimal higher-derivative supergravity theories extending the f (R) gravity, towards their use for the inflationary model building in supergravity, by using both superfields and their field components.

Enriques and Octonionic Magic Supergravity Models

, 2007
We reconsider the Enriques Calabi Yau (FHSV) model and its string derivation and argue that the Octonionic magic supergravity theory admits a string interpretation closely related to the Enriques model.
