Inflation and cosmic (super)strings: implications of their intimate relation revisited

TL;DR

This paper reviews the constraints on inflationary models, especially brane inflation, from recent cosmic microwave background data, focusing on the implications of cosmic (super)string tensions for these theories.

Contribution

It revisits the relationship between inflation and cosmic (super)strings, analyzing how recent observational constraints impact theoretical models.

Findings

Strong constraints on cosmic (super)string tension from CMB data.

Implications for the viability of brane inflation models.

Reassessment of supersymmetric hybrid inflation models.

Abstract

We briefly discuss constraints on supersymmetric hybrid inflation models and examine the consistency of brane inflation models. We then address the implications for inflationary scenarios resulting from the strong constraints on the cosmic (super)string tension imposed from the most recent cosmic microwave background temperature anisotropies data.
