Big bang nucleosynthesis constraints on higher-order modified gravities
We use big bang nucleosynthesis (BBN) data in order to impose constraints on higher-order modified gravity and, in particular, on (i) f(G) Gauss-Bonnet gravity and f(P) cubic gravities arising, respectively, through the use of the quadratic-curvature Gauss-Bonnet G term and the cubic-curvature combi...
