The one-loop bispectrum of galaxies in redshift space from the Effective Field Theory of Large-Scale Structure

Understand

We derive the kernels and the Effective Field Theory of Large-Scale Structure counterterms for the one-loop bispectrum of dark matter and of biased tracers in real and redshift space.

• This requires the expansion of biased tracers up to fourth order in fluctuations.
• In the process, we encounter several subtleties related to renormalization.
• One is the fact that, in renormalizing the momentum, a local counterterm contributes non-locally.
