Constraints on Single-Field Inflation from the BOSS Galaxy Survey
We present constraints on non-local primordial non-Gaussianity (NLPNG) from the Baryon Oscillation Spectroscopic Survey data. We first review how NLPNG arises in single-field inflationary models. We then review the Effective Field Theory of Large-Scale Structure, the main tool that allowed us to obtain constraints on NLPNG. Finally, we show how our constraints on NLPNG map to bounds on the coefficients of the effective Lagrangian of single-field inflation.
