Probing Screening and the Graviton Mass with Gravitational Waves

Gravitational waves have been used previously to constrain many fundamental quantities in physics, including the mass of the graviton. However, these bounds have neglected the effect of screening, which is typically present in modified theories that predict a non-zero graviton mass. In this talk, I will first show how a previously derived correction to the propagation of gravitational waves sourced by a massive graviton is affected by screening processes. After that, I will present the numerical results we have obtained that predict how well future gravitational wave detectors can constrain the screened graviton mass in a model-independent interpretation. As screening effects and modifications to General Relativity are competing effects, this will define a degenerate bound on the screening radius and the graviton mass.
