Dynamical Compactification and Inflation in Einstein-Yang-Mills Theory with Higher Derivative Coupling
Hironobu Kihara, Muneto Nitta, Misao Sasaki +2
We study cosmology of the Einstein-Yang-Mills theory in ten dimensions with a quartic term in the Yang-Mills field strength. We obtain analytically a class of cosmological solution…
Gravitational reheating in quintessential inflation
E. J. Chun, S. Scopel, I. Zaballa
We provide a detailed study of gravitational reheating in quintessential inflation generalizing previous analyses only available for the standard case when inflation is followed by…
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…
