CMB Tensor Anisotropies in Metric f(R) Gravity

arXiv:1202.3862 · doi:10.1063/1.4734430

Abstract

We present a description of CMB anisotropies generated by tensor perturbations in f(R) theories of gravity. The temperature power spectrum in the special case of $f(R)=R^n$ is computed using a modified version of CAMB package.
