This work is a detailed study of both the theoretical and
phenomenological consequences of a massive graviton, within the
ghost-free theory of massive gravity, the de Rham-Gabadadze-Tolley
(dRGT) theory. Its aim is to test the physical viability of the
theory. It begins by putting constraints on the parameters of the
theory in the decoupling limit based on purely theoretical grounds,
like classical stability in the cosmological evolution of
self-accelerating and degravitating solutions. The author then
constructs a proxy theory to massive gravity from the decoupling
limit resulting in non-minimally coupled scalar-tensor interactions
as an example of a subclass of Horndeski theories. Lastly, she
addresses the natural question of whether the parameters introduced
in the dRGT theory are subject to strong renormalization by quantum
loops and shows how the non-renormalization theorem protects the
graviton mass from quantum corrections. Beyond the decoupling limit
the quantum corrections are found to be proportional to the
graviton mass, proving its technical naturalness.
