Comments on scattering in massive gravity, vDVZ and BCFW [CL]

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.
