CMB anomalies and the effects of local features of the inflaton potential
ABSTRACT: Recent analysis of the WMAP and Planck data have shown the presence of a dip and a bump in the spectrum of primordial perturbations at the scales k = 0.002 Mpc−1 and k = 0.0035 Mpc−1, respectively. We analyze for the first time the effects of a local feature in the inflaton potential to ex...
