Graviton and scalar propagations on AdS(4) space in f(R) gravities
arXiv:1012.2153 · doi:10.1140/epjc/s10052-011-1550-4
Abstract
We investigate propagations of graviton and additional scalar on four-dimensional anti de Sitter (AdS) space using gravity models with external sources. It is shown that there is the van Dam-Veltman-Zakharov (vDVZ) discontinuity in gravity models because gravity implies GR with additional scalar. This indicates a difference between general relativity and gravity clearly.
