Non-minimal derivative coupling theories compatible with GW170817
In this work we aim to revive the interest for non-minimal derivative coupling theories of gravity, in light of the GW170817 event. These theories include a string motivated non-minimal kinetic term for the scalar field of the form ∼ξ(ϕ)Gμν∂μϕ∂νϕ and predict that the primordial tensor perturbations...
