Explore advanced theoretical developments in Large Scale Structure (LSS) cosmology through this 28-minute conference talk that delves into higher-order loop calculations and their implications for understanding cosmic structure formation. Learn about the mathematical frameworks and computational techniques used to extend perturbative approaches beyond leading-order approximations in LSS analysis. Discover how higher-loop corrections contribute to more accurate predictions of galaxy clustering, matter power spectra, and other observational quantities in cosmological surveys. Examine the challenges and recent progress in implementing these sophisticated calculations, including regularization schemes, renormalization procedures, and the treatment of non-linear effects in cosmic structure evolution. Gain insights into how these theoretical advances connect to current and future observational programs aimed at constraining dark matter, dark energy, and fundamental cosmological parameters through precision measurements of large-scale cosmic structures.
