Abstract

We investigate propagations of graviton and additional scalar on four-dimensional anti de Sitter (AdS4_4) space using f(R)f(R) gravity models with external sources. It is shown that there is the van Dam-Veltman-Zakharov (vDVZ) discontinuity in f(R)f(R) gravity models because f(R)f(R) gravity implies GR with additional scalar. This indicates a difference between general relativity and f(R)f(R) gravity clearly.
