Deformed Starobinsky model in gravity’s rainbow
Abstract In the context of gravity’s rainbow, we study the deformed Starobinsky model in which the deformations take the form $$f(R)\sim R^{2(1-\alpha )}$$ f(R)∼R2(1-α) , with R and $$\alpha $$ α being the Ricci scalar and a positive parameter, respectively. We show that the spectral index of curvat...
