Primordial Black Holes and Local Non-Gaussianity in Canonical Inflation
Samuel Passaglia, Wayne Hu, Hayato Motohashi
Primordial black holes (PBHs) cannot be produced abundantly enough to be the dark matter in canonical single-field inflation under slow roll. This conclusion is robust to local non…

Scalar Bispectrum Beyond Slow-Roll in the Unified EFT of Inflation
Samuel Passaglia, Wayne Hu
We present a complete formulation of the scalar bispectrum in the unified effective field theory (EFT) of inflation, which includes the Horndeski and beyond-Horndeski Gleyzes-Langl…

Reconciling tensor and scalar observables in G-inflation
Héctor Ramírez, Samuel Passaglia, Hayato Motohashi +2
The simple potential as an inflationary model is coming under increasing tension with limits on the tensor-to-scalar ratio and measurements of the scalar spectral inde…
