A bstract We explicitly compute the component action of certain recently discovered
new\(\mathcal {N}\)= 1 supergravity actions which enlarge the space of scalar potentials …

A bstract We compute the 2→ 2 gravitino scattering amplitudes at tree level in supergravity
theories where supersymmetry is spontaneously broken. In the unitary gauge, the gravitino …

A new supergravity D-term, not associated to gauged R-symmetry, was recently discovered
and used to construct new supergravity models. In this paper we use a generalization of the …

A model of supergravity inflation we recently proposed can produce slow roll inflation and a
realistic spectrum of particles even without F-term supersymmetry breaking. Supersymmetry …

We propose a novel class of $\mathcal {N}= 1$ supergravity (called``Relaxed supergravity'')
that can enlarge the space of scalar potentials, relaxing the strongly-constrained form of the …

A bstract We study supersymmetry breaking from a complex linear superfield coupled to 4D
N= 1 supergravity. The theory has two classically decoupled vacua, one supersymmetric …

Supergravity, a locally supersymmetric gauge theory, may provide to describe new physics
beyond the Standard Model (BSM), such as slow-roll inflation, the cosmological constant …

We present the proposal that the superpartner of the goldstino (sgoldstino), which is the
source of the supersymmetry breaking, acts as the inflaton. The so-called eta problem can …

We review recent developments on generalised Fayet-Iliopoulos D-terms in fourdimensional
supergravity and discuss their applications to natural models of inflation driven by …
