Big Bang Nucleosynthesis constraints on higher-order modified gravities

Petros Asimakis, Spyros Basilakos, Nick E. Mavromatos +1

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…
