Query: Relaxed Supergravity   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 prototype supergravity potential. It has very
long been considered that in $\mathcal{N}=1$ supergravity a negative term of
scalar potential can be given only by the gravitino-mass term (i.e. $-3e^{G}$)
from the F-term potential, while such negative term is absent in global
supersymmetry (SUSY). In this letter, however, we firstly discover a new
negative-definite contribution to the scalar potential in $\mathcal{N}=1$
supergravity and even global SUSY. In the end, this allows us to have a general
scalar potential. To achieve this, we start with detection of a ``no-go''
theorem for the higher order corrections in minimal supergravity models of
inflation, which was investigated by Ferrara, Kallosh, Linde, and Porrati
(FKLP). Based on the no-go theorem, we establish a superconformal action of a
certain higher order correction for generating the new negative term. Then, we
identify essential constraints on the new negative term by inspecting the
suppression of the nonrenormalizable terms. We find that relaxed supergravity
has a cutoff equal to SUSY breaking scale $M_S$. This signals that
supersymmetry may be broken at high scale according to the cutoff leaving the
naturalness issue aside. We suggest that relaxed supergravity can be a
universal framework for building supergravity models of various phenomenologies
under broken SUSY from particle physics to cosmology.
