The coupling of non-linear supersymmetry to supergravity
Résumé
We study the coupling of non-linear supersym-metry to supergravity. The goldstino nilpotent superfield of global supersymmetry coupled to supergravity is described by a geometric action of the chiral curvature superfield R subject to the constraint (R − λ) 2 = 0 with an appropriate constant λ. This constraint can be found as the decoupling limit of the scalar partner of the goldstino in a class of f (R) supergravity theories.
