Title: Novel results in perturbation theory for LSS
Date (JST): Fri, Apr 03, 2026, 15:30 - 17:00
Place: Seminar Room A
Abstract:
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.
