Refined predictions for Starobinsky inflation and post-inflationary constraints in light of ACT
Recent measurements from the Atacama Cosmology Telescope (ACT), combined with Planck and DESI data, suggest a higher value for the spectral index ns. This places Starobinsky inflation at the edge of the 2σ constraints for a number of e-folds N⋆ around 60 when using the usual analytical approximation...
