Tighter bounds on a hypothetical graviton screening mass from the gravitational wave observation GW150914 at LIGO
arXiv:1602.04337
Abstract
While quantum gravity is not solved yet, a screening mass for the graviton remains theoretically possible. If such a mass would screen gravity at distances of the order of the cluster galaxy radius, it could account for the universe expansion. The modified Newtonian dynamics model also could be related to a screening graviton mass at inter-galactic scales. Moreover, massive spin-2 theories constitute a very active theoretical topic. We briefly show how the very recent LIGO gravitational wave observation GW150914, emitted by a binary black hole merger distant ly from the Earth, tightens the phenomenological bound on a massive graviton or on the screening of gravity.
