Confronting mukhanov parametrization of inflationary equation-of-State with ACT-DR6
Abstract
We provide a simple yet effective semi-analytical approach to confront Mukhanov Parametrization of inflationary equation-of-state, $1+ω=\fracβ{({N}+1)^α}$, with the latest ACT-DR6 data employing Hamilton-Jacobi formulation. We find that equation-of-state formalism comes up with excellent fit to the latest data. In the process we are also able to put stringent constraint on the two model parameters. In order to get the bounds of $α$ and $β$ we have also made use of the recent finding $r
