Gravitational radiation from binary systems in massive graviton theories

Understand

Theories with massive gravitons have peculiarity called the van Dam-Veltman-Zakharov discontinuity in that the massive theory propagator does not go to the massless graviton propagator in the zero graviton mass limit.

• This results in large deviation in Newtons law for massive graviton theories even when the graviton mass vanishes.
• We test the vDVZ in massive graviton theories for single graviton vertex process namely the gravitational radiation from a classical source.
• We calculate the gravitational radiation from compact binaries using the perturbative Feynman diagram method.
