Testing scalar-tensor theories and parametrized post-Newtonian parameters in Earth orbit
Testing scalar-tensor theories and parametrized post-Newtonian parameters in Earth orbit
We compute the parametrized post-Newtonian (PPN) parameters $\ensuremath{\gamma}$ and $\ensuremath{\beta}$ for general scalar-tensor theories in the Einstein frame, which we compare to the existing PPN formulation in the Jordan frame for alternative theories of gravity. This computation is important for scalar-tensor theories that are expressed in the Einstein frame, such …
