R2-corrected Tachyon Scalar Field Inflation, the ACT Data, and Phantom Transition
Phantom divide line transitions are not possible in the context of single scalar field scalar-tensor theories. In this article we study a combined framework of a tachyonic minimally coupled single scalar field theory in the presence of an R2 correction term and with a rescaled Einstein-Hilbert term...
