Constraints on the primordial curvature perturbation from primordial black holes
Ignacio Zaballa, Anne M. Green, Karim A. Malik +1
We calculate the constraints on the primordial curvature perturbation at the end of inflation from the present day abundance of Primordial Black Holes (PBHs), as a function of the…
Higher order contributions to the primordial non-gaussianity
Ignacio Zaballa, Yeinzon Rodriguez, David H. Lyth
In this paper we calculate additional contributions to that part of the non-Gaussianity of the curvature perturbation, which come from the three-point correlator of the field pertu…
Forming sub-horizon black holes at the end of inflation
David. H Lyth, Karim A. Malik, Misao Sasaki +1
Previous authors have calculated the mass function of primordial black holes only on scales which are well outside the horizon at the end of inflation. Here we extend the calculati…
A Bound Concerning Primordial Non-Gaussianity
David H. Lyth, Ignacio Zaballa
Seery and Lidsey have calculated the three-point correlator of the light scalar fields, a few Hubble times after horizon exit during inflation. Lyth and Rodriguez have calculated t…
