Abstract Minimal supersymmetric hybrid inflation utilizes a canonical Kahler potential and a renormalizable superpotential which is uniquely determined by imposing a U(1) R -symmetry. In computing the scalar spectral index n s we take into account modifications of the tree level potential caused by radiative and supergravity corrections, as well as contributions from the soft supersymmetry breaking terms with a negative soft mass-squared term allowed for the inflaton. All of these contributions…

Update on Minimal Supersymmetric Hybrid Inflation in Light of PLANCK
The minimal supersymmetric (or F-term) hybrid inflation is d efined by a unique renormalizable superpotential, fixed by a U(1) R-symmetry, and it employs a canonical Kahler potential. The
Gravity waves and gravitino dark matter in μ-hybrid inflation
Abstract We propose a novel reformulation of supersymmetric (more precisely μ-) hybrid inflation based on a local U(1) or any suitable extension of the minimal supersymmetric standard model (MSSM)
Non-Minimal Higgs Inflation and non-Thermal Leptogenesis in A Supersymmetric Pati-Salam Model
We consider a supersymmetric (SUSY) Grand Unified Theory (GUT) based on the gauge group GPS = SU(4)C × SU(2)L × SU(2)R, which incorporates non-minimal chaotic inflation, driven by a quartic potential
Modern constraints on F-term SUSY hybrid inflation models
We study modifications of supersymmetric hybrid inflation, which continues to be one of the most popular inflationary models. The seminal formulation considered the VG+∆V potential, in which one can
Symmetry breaking and reheating after inflation in no-scale flipped SU(5)
No-scale supergravity and the flipped SU(5)×U(1) gauge group provide an ambitious prototype string-inspired scenario for physics below the string scale, which can accommodate the Starobinsky-like
Phenomenology with F-theory SU(5)
We explore the low energy phenomenology of an F-theory based SU(5) model which, in addition to the known quarks and leptons, contains Standard Model singlets, and vector-like color triplets and SU(2)
Constrained supersymmetric flipped SU(5) GUT phenomenology
We explore the phenomenology of the minimal supersymmetric flipped SU(5) GUT model (CFSU(5)), whose soft supersymmetry-breaking (SSB) mass parameters are constrained to be universal at some input
μ -hybrid inflation with low reheat temperature and observable gravity waves
In $\mu$-hybrid inflation a nonzero inflaton vacuum expectation value induced by supersymmetry breaking is proportional to the gravitino mass $m_{3/2}$, which can be exploited to resolve the minimal
Axion isocurvature perturbations in low-scale models of hybrid inflation
The QCD axion solves the strong CP problem and represents an attractive particle candidate for cold dark matter (CDM). However, quantum fluctuations of the axion field during inflation easily result
Sneutrino driven GUT inflation in supergravity
A bstractIn this paper, we embed the model of flipped GUT sneutrino inflation — in a flipped SU(5) or SO(10) set up — developed by Ellis et al. in a supergravity framework. The GUT symmetry is broken


Supersymmetric hybrid inflation redux
Abstract We discuss the important role played during inflation by one of the soft supersymmetry breaking terms in the inflationary potential of supersymmetric hybrid inflation models. With minimal
Testing supersymmetric grand unified models of inflation
Abstract We reconsider a class of well motivated supersymmetric models in which inflation is associated with the breaking of a gauge symmetry G to H, with the symmetry breaking scale M∼1016 GeV.
Fermion mass textures in an M-inspired flipped SU(5) model derived from string
Abstract We are inspired by the facts that M theory may reconcile the supersymmetric GUT scale with that of quantum gravity, and that it provides new avenues for low-energy supersymmetry breaking, to
Supersymmetric hybrid inflation with non-minimal Kähler potential
Abstract Minimal supersymmetric hybrid inflation based on a minimal Kahler potential predicts a spectral index n s ≳ 0.98 . On the other hand, WMAP three year data prefers a central value n s ≈ 0.95
Inflation and monopoles in supersymmetric SU(4)c × SU(2)L × SU(2)R
We show how hybrid inflation can be successfully realized in a supersymmetric model with gauge group GPS = SU(4)c ? SU(2)L ? SU(2)R. By including a non-renormalizable superpotential term, we generate
Supersymmetric flipped SU(5) revitalized
Abstract We describe a simple N = 1 supersymmetric GUT based on the group SU(5)×U(1) which has the following virtues: the gauge group is broken down to the SU (3) C × SU (2) L × U (1) Y of the
Top quark mass in supersymmetric SO(10) unification.
The successful prediction of the weak mixing angle suggests that the effective theory beneath the grand unification scale is the minimal super- symmetric standard model (MSSM) with just two Higgs doublets, and the top quark mass can be predicted in terms of the MSSM parameters.
Supergravity as the messenger of supersymmetry breaking
A systematic study is made of theories in which supergravity is spontaneously broken in a ''hidden'' sector of superfields that interact with ordinary matter only through supergravity. General rules
Confronting hybrid inflation in supergravity with CMB data
F-term GUT inflation coupled to N = 1 supergravity is confronted with CMB data. Corrections to the string mass-per-unit-length away from the Bogomolny limit are taken into account. We find that a
Reducing the spectral index in F-term hybrid inflation
We consider a class of well motivated supersymmetric models of F-term hybrid inflation (FHI) which can be linked to the supersymmetric grand unification. The predicted scalar spectral index n_s
