Abstract |
We describe in detail the Supersymmetric Completion of the R+R2 Starobinsky model of Inflation in different (old,new) minimal off-shell extensions of Supergravity, which propagate different degrees of freedom in “fourth order” actions. |

Title |
Supersymmetry and Inflation | |||||
| Coauthors | ||||||||

Abstract |
Theories with elementary scalar degrees of freedom seem nowadays to be required for simple descriptions of the Standard Model of fundamental particle interactions and of the early evolution of the Universe. A space-time symmetry, consistent with Relativistic Quantum Field Theory, which naturally accommodates scalar fields is Supersymmetry, and supersymmetric extensions of the Standard Model with their predictions are under scrutiny at the Large Hadron Collider (LHC). It is then natural to embed theories of inflation in the Supergravity context, also in view a possible ultraviolet completion in SuperString Theory. After a brief description of the general framework of inflation in Supergravity, minimal models for inflaton dynamics which are compatible with recent observations from PLANCK and BICEP experiments are presented, and different scenarios of Supersymmetry Breaking during and after inflation will be discussed |
