Abstract

We provide a succinct way to construct the supersymmetric completion of RnR^n (n3)(n\ge3) in components using superconformal formulation of old minimal supergravity. As a consequence, we obtain the polynomial f(R)f(R) supergravity extending the supersymmetric Starobinsky model to any higher power of RR. The supersymmetric vacua in polynomial f(R)f(R) supergravity are studied. We also present the RnR^n extended Minimal Volkov-Akulov-Starobinsky Model.
