Is There Scale-Dependent Bias in Single-Field Inflation?

de Putter, Roland, Doré, Olivier, Green, Daniel

Understand

Scale-dependent halo bias due to local primordial non-Gaussianity provides a strong test of single-field inflation.

While it is universally understood that single-field inflation predicts negligible scale-dependent bias compared to current observational uncertainties, there is still disagreement on the exact level of scale-dependent bias at a level that could strongly impact inferences made from future surveys.
In this paper, we clarify this confusion and derive in various ways that there is exactly zero scale-dependent bias in single-field inflation.
Much of the current confusion follows from the fact that single-field inflation does predict a mode coupling of matter perturbations at the level of $f_{NL}^{loc} \approx -5/3$, which naively would lead to scale-dependent bias.
