Planck 2018 and brane inflation revisited

Abstract We revisit phenomenological as well as string-theoretical aspects of D-brane inflation cosmological models. Phenomenologically these models stand out on par with α-attractors, as models with Planck-compatible values of n s , moving down to the sweet spot in the data with decreasing value of...
