An effective field theory approach to cosmology

Abstract

Precision cosmological observations from the cosmic microwave background (CMB) and large scale structures (LSS) during the last few decades have re-shaped our attempts at understanding the universe we inhabit.Physicists today are thus combining top down ideas such a string theory, with bottom up routes or effective field theories (EFTs), similar to those used in particle physics. This proposal is mostly about the latter, and implementing a systematic EFT approach to the physics of the early and late universe. This program resembles the uses of EFTs in particle physics which play a crucial role in elucidating the nature of electroweak symmetry breaking at the Large Hadron Collider. My research group will thus contribute to position ICTP-SAIFR as a leading centre for EFT applications in cosmology in the advent of a new generation of experimental probes of the universe. (AU)
