چکیده
We discuss supergravity inflation in braneworld cosmology for the class of potentials [Formula: see text] with text]. These minimal SUGRA models evade problem due to a broken shift symmetry and can easily accommodate observational constraints. In high energy regime text], numerical predictions approximate analytic formulas are given scalar spectral index tensor-to-scalar ratio The smaller preferred while larger out region. Remarkably, correction density Friedmann equation results sub-Planckian inflaton excursions

WMAP Bounds on Braneworld Tachyonic Inflation
We analyse the implications of the Wilkinson Microwave Anisotropy Probe (WMAP) results for a braneworld tachyonic model of inflation. We find that WMAP bounds on ns allow us to constrain significantly the parameter space of the model; in particular, extremely weak string coupling is required, gs ∼ 10. Moreover, our analysis shows that the running of the scalar spectral index is within the bound...
متن کاملNatural braneworld inflation and baryogenesis
In natural inflation models, the inflaton is a pseudo Nambu-Goldstone boson and the flatness of the potential is protected by shift symmetries. In this framework, a successful inflation requires the global symmetry to be spontaneously broken at a scale close to the Planck mass. Such a high value of the spontaneous breaking scale may not be legitimate in an effective field theory. On the other h...
متن کاملOn the possibility of braneworld quintessential inflation
We examine the possibility of achieving quintessential inflation, where the same field serves as both inflaton and quintessence, in the context of a five-dimensional braneworld. Braneworld cosmology provides an appropriate environment as it permits inflation with much steeper potentials than the conventional scenario, which is favorable to a late-time quintessence. We explore a wide space of mo...
متن کاملHybrid Inflation in Supergravity
For the last 15 years cosmologists believe that something like inflation is necessary in order to construct an internally consistent cosmological theory. For more than 20 years the best hopes for the theory of all fundamental interactions are related to supersymmetry. Unfortunately it is not that simple to combine these two ideas. The main problem is that the effective potential for the inflato...
متن کاملTopological Inflation in Supergravity
We investigate a topological inflation model in supergravity. By means of numerical simulations, it is confirmed that topological inflation really takes place in supergravity. We also show that the condition for successful inflation depends not only on the vacuum-expectation value (VEV) of inflaton field but also on the form of its Kähler potential. In fact, it is found that the required VEV of...
