Refined swampland conjecture in deformed Starobinsky gravity

In order to validate or invalidate a large class of low energy effective theories, the swampland conjecture has attracted significant attention recently. It can be stated as inequalities on potential scalar field which is conjectured satisfy certain constraints. this work, we discuss theoretical viability deformed Starobinsky gravity in light refined conjectures. We consider deformation form [Formula: see text] with being constant. then constrain using spectral index curvature perturbation and tensor-to-scalar ratio text]. demonstrate that model under consideration strong tension conjecture. However, regarding our analysis proper choices parameters text], discover always new Therefore, might “landscape” since “further refining de Sitter conjecture” satisfied.
