Comments on scattering in massive gravity, vDVZ and BCFW

Abstract

Armed with the latest technology in the computation of scattering amplitudes involving massive particles of any spin, we revisit the van Dam-Veltman-Zakharov (vDVZ) discontinuity of massive gravity and show how it may be understood in terms of the Britto-Cachazo-Feng-Witten (BCFW) relations.
