Superconformal attractor E-models in brane inflation under swampland criteria

Presented by Mr. Mudassar SABIR on 2 Jul 2019 from 15:30 to 15:50
Type: oral presentation
Track: String Theory and Alternatives


The effective field theory of cosmic inflation has been highly constrained by the swampland conditions recently. In brane inflation the Friedmann equation is modified to include an additional parameter λ called brane tension that modifies the slow-roll parameters such that the restrictive swampland conditions can be naturally evaded. We discuss superconformal α-attractor E-models that are consistent with distance conjecture and the further refined de Sitter conjecture. We derive an analytic formulae for n_s and r that approximates the accurate results very well. This class of models satisfies various consistency requirements and is also consistent with the Planck 2018 and BICEP2 observational constraints on n_s and r.
