Starobinsky Model in N=2 Supergravity

Abstract

The Starobinsky inflationary model of $(R+R^2)$ gravity is extended to the new-minimal (40+40) off-shell 4D, N=2 supergravity in N=2 chiral (curved) superspace. In its dual formulation, as a matter-coupled N=2 Einstein supergravity, inflaton belongs to a massive N=2 vector multiplet.
