On interactions of higher spin fields with gravity and branes in AdS_5
Cristiano Germani, Arabella Schelpe
We construct actions of higher spin fields interacting with gravity on AdS_5 backgrounds such that the Compton scattering amplitudes of the interaction are tree-level unitary. We t…
Matching WMAP 3-yrs results with the Cosmological Slingshot Primordial Spectrum
Cristiano Germani, Michele Liguori
We consider a recently proposed scenario for the generation of primordial cosmological perturbations, the so called Cosmological Slingshot scenario. We firstly obtain a general exp…
The Cosmological Slingshot Scenario: Myths and Facts
Cristiano Germani, Nicolas Grandi, Alex Kehagias
We generalize the Cosmological Slingshot Scenario for a Slingshot brane moving in a Klebanov-Strassler throat. We show that the horizon and isotropy problems of standard cosmology…
On the Onset of Inflation in Loop Quantum Cosmology
Cristiano Germani, William Nelson, Mairi Sakellariadou
Using a Liouville measure, similar to the one proposed recently by Gibbons and Turok, we investigate the probability that single-field inflation with a polynomial potential can las…
