Constraining SUSY GUTS with Cosmology
Mairi Sakellariadou, Jonathan Rocher

TL;DR
This paper examines how cosmic strings formed during supersymmetric hybrid inflation impact cosmological observations, constraining inflationary model parameters based on recent CMB data.
Contribution
It provides new constraints on SUSY GUT inflationary models by analyzing the effects of cosmic strings on CMB anisotropies.
Findings
Cosmic strings at the GUT scale are compatible with current CMB data.
String contributions impose limits on inflationary parameters.
Constraints help refine SUSY GUT inflation models.
Abstract
Cosmic strings of the GUT scale, generically formed during the SSB of supersymmetric hybrid inflation, are compatible with the most recent CMB data. The strong constraints on the allowed cosmic strings contribution to the measured temperature anisotropies impose limits on the free parameters of the inflationary models, namely the mass scales and the couplings.
