Quantum gravity and the large scale anomaly
Abstract
The spectrum of primordial perturbations obtained by calculating the quantum gravitational corrections to the dynamics of scalar perturbations is compared with Planck 2013 and BICEP2/Keck Array public data. The quantum gravitational effects are calculated in the context of a WheelerDe Witt approach and have quite distinctive features. We constrain the free parameters of the theory by comparison with observations.
