Rich tapestry: Supersymmetric axions, dark radiation, and inflationary reheating
Rich tapestry: Supersymmetric axions, dark radiation, and inflationary reheating
We exploit the complementarity among supersymmetry, inflation, axions, Big Bang Nucleosynthesis (BBN) and Cosmic Microwave Background Radiation (CMB) to constrain supersymmetric axion models in the light of the recent Planck and BICEP results. In particular, we derive BBN bounds coming from altering the light element abundances by taking into account …
