Efficiently evaluating loop integrals in the EFTofLSS using QFT integrals with massive propagators

open access: yesJournal of High Energy Physics
We develop a new way to analytically calculate loop integrals in the Effective Field Theory of Large Scale-Structure. Previous available methods show severe limitations beyond the one-loop power spectrum due to analytical challenges and computational and

General covariant transition amplitudes in quantum cosmology

open access: yes, 2011
The path-integral approach to cosmology consists in the computation of transition amplitudes between states of the quantum geometry of the universe.
