Description
Major improvements in the theoretical understanding of LSS have been possible due to the effective field theory approach. After an overview of the perturbation theory applications for LSS, I will discuss how to go beyond the one-loop calculation, presenting novel two-loop results and their information content (both for clustering and lensing). I will also show how to extract information from higher-loop orders using renormalization group equations.
