Minicourse on Effective Field Theory in Large Scale Structure

The Effective Field Theory of Large-Scale Structure (EFTofLSS) provides a powerful theoretical framework for understanding the distribution of matter and galaxies in the universe on cosmological scales. This course introduces the key developments in EFTofLSS, emphasizing its role in bridging theoretical physics with observational data from galaxy surveys.

There is no registration.
