Vacuum structure in a chiral $R+R^n$ modification of pure supergravity
We discuss an ${\cal R}+{\cal R}^n$ class of modified ${\cal N}=1$, D=4 supergravity models where the deformation is a monomial ${\cal R}^n\big|_F$ in the chiral scalar curvature multiplet ${\cal R}$ of the "old minimal" auxiliary field formulation. The scalaron and goldstino multiplets ar...
