f ( R ) gravity inflation with string-corrected axion dark matter

It is quite well known that string-inspired axionic terms of the form ν ( ϕ ) ˜ R R , known also as Chern-Simons terms, do not affect the scalar perturbations and the background evolution for a flat Friedman-Robertson-Walker universe. In this paper, we study and quantify the implications of the pres...
