Contribution

It provides the first detailed analysis of solar system tests for massive conformal gravity, establishing bounds on the graviton mass.

Findings

Theory agrees with general relativity in the solar system

Established a lower bound on the graviton mass

Demonstrated viability of massive conformal gravity in solar system tests

Abstract

We find the linearized gravitational field of a static spherically symmetric mass distribution in massive conformal gravity and test it with some solar system experiments. The result is that the theory agrees with the general relativistic observations in the solar system for a determined lower bound on the graviton mass.
