Inflation from high-scale supersymmetry breaking

Supersymmetry breaking close to the scale of grand unification can explain cosmic inflation. As we demonstrate in this paper, this can be achieved in strongly coupled supersymmetric gauge theories,

Dynamical supersymmetry breaking and late-time R symmetry breaking as the origin of cosmic inflation

Spontaneously broken supersymmetry (SUSY) and a vanishingly small cosmological constant imply that $R$ symmetry must be spontaneously broken at low energies. Based on this observation, we suppose

Inflationary Model and M-theory

A proposal is made for a cosmological D3/D7 model with a constant magnetic flux along the D7 world-volume. It describes an N = 2 gauge model with FayetIliopoulos terms and the potential of the hybrid

De Sitter vacua and the landscape of string theory

In this pedagogical lecture we explain some basic part of the standard cosmological model which is most relevant for the fundamental theoretical physics. We stress the common features and differences

Supergravity Analysis of Hybrid Inflation Model from D3--D7 System - eScholarship

The slow-roll inflation is a beautiful paradigm, yet the inflaton potential can hardly be sufficiently flat when unknown gravitational effects are taken into account. However, the hybrid inflation

P-term, D-term and F-term inflation

P-term inflation is a version of hybrid inflation which naturally appears in some brane inflation models. It was introduced in the framework of N = 2 supersymmetric gauge theory where superconformal

Supergravity, M theory and Cosmology

We discuss some recent attempts to reconcile cosmology with supergravity and M/string theory. First of all, we point out that in extended supergravities the scalar masses are quantized in terms of

D3-D7 inflationary model and M theory

A proposal is made for a cosmological D3-D7 model with a constant magnetic flux along the D7 world volume. It describes an $\mathcal{N}=2$ gauge model with Fayet-Iliopoulos terms and the potential of
