Supersymmetry Breaking by Higher Dimension Operators
Fotis Farakos, Sergio Ferrara, Alex Kehagias +1
We discuss a supersymmetry breaking mechanism for N = 1 theories triggered by higher dimensional op- erators. We consider such operators for real linear and chiral spinor superfiel…
On the Starobinsky Model of Inflation from Supergravity
F. Farakos, A. Kehagias, A. Riotto
We discuss how the higher-derivative Starobinsky model of inflation originates from N=1 supergravity. It is known that, in the old-minimal supergravity description written by emplo…
On Ghost-free Supersymmetric Galileons
Fotis Farakos, Cristiano Germani, Alex Kehagias
We present consistent supersymmetric theories invariant under the generalization of the Galilean shift symmetry to superspace. These theories are constructed via the…
Emergent Potentials in Consistent Higher Derivative N=1 Supergravity
Fotis Farakos, Alex Kehagias
By employing consistent supersymmetric higher derivative terms, we show that the supersymmetric theories may have a sector where the scalar potential does no longer have the conven…
Decoupling Limits of sGoldstino Modes in Global and Local Supersymmetry
Fotis Farakos, Alex Kehagias
We study the decoupling limit of a superheavy sgoldstino field in spontaneously broken N=1 supergravity. Our approach is based on Kähler superspace, which, among others, allows dir…
