Description
In this talk, I will first present the paradigm of the effective field theory of large-scale structure (EFTofLSS), a semi-analytical method which provides an accurate description of the power spectrum and bispectrum of bias tracers, and aims at improving cosmological constraints from large-scale structure surveys, a major challenge in the context of DESI and the forthcoming Euclid mission. Second, I will present some possible applications of this theory and show its potential to enhance our understanding of non-standard hypotheses concerning the dark sector and the initial conditions of the Universe.
