Ghost-free non-local F(R) gravity compatible with ACT
We confront the ghost-free non-local F(R) gravity theories with the latest Atacama Cosmology Telescope (ACT) constraints on the spectral index of the scalar perturbations and the updated constraints of Planck/BICEP on the tensor-to-scalar ratio. After reviewing how the ghost-free non-local version o...
