Two-loop QCD correction to massive spin-2 Graviton decaying to $q ~ + ~\bar{q}~ + ~g$ is presented considering a generic universal spin-2 coupling tothe SM through the conserved energy-momentum tensor. Such a massive spin-2particle can arise in extra-dimensional models. The ultraviolet and infraredstructure of the QCD amplitudes are studied. In dimensional regularisation, theinfrared pole structure is in agreement with Catani's proposal, confirming theuniversal factorization property of QCD amplitudes, even with the spin-2tensorial coupling. This computation now completes the full two-loop QCDcorrections for the production of a spin-2 in association with a jet.
