We develop a string-inspired model for particle cosmology, based on a flipped SU (5)× U (1)
gauge group formulated in a no-scale supergravity framework. The model realizes …

We have presented previously a general treatment of Starobinsky-like inflation in no-scale
supergravity where the tensor-to-scalar ratio r= 3 (1− ns) 2, and ns is the tilt of the scalar …

We have recently proposed attractor models for modulus fixing, inflation, supersymmetry
breaking and dark energy based on no-scale supergravity. In this paper we develop …

No-scale supergravity provides a successful framework for Starobinsky-like inflation models.
Two classes of models can be distinguished depending on the identification of the inflaton …

We have realized non-minimal Higgs inflation and standard hybrid inflation in the
supersymmetric flipped SU (5) model with U (1) R symmetry using the no-scale form of the …

We show the uniqueness of superpotentials leading to Minkowski vacua of single-field no-
scale supergravity models, and the construction of dS/AdS solutions using pairs of these …

Recently, it has been shown that the presence of a noninstantaneous era of reheating can
significantly alter the charged lepton (s) equilibration temperature (s) which plays an …

We propose a non-oscillatory no-scale supergravity model of inflation (NO-NO inflation) in
which the inflaton does not oscillate at the end of the inflationary era. Instead, the Universe is …

We show that the process of noninstantaneous reheating during the postinflationary period
can have a sizable impact on the charged lepton Yukawa equilibration temperature in the …

We propose the generic no-scale inflation inspired from string theory compactifications. We
consider the Kähler potentials with an inflaton field φ, as well as one, two, and three Kähler …
