Abstract:
The two-loop QCD correction to massive spin-2 graviton decaying to q+ q¯ + g is presented considering a generic universal spin-2 coupling to the SM through the conserved energy-momentum tensor. Such a massive spin-2 particle can arise in extra-dimensional models. The ultraviolet and infrared structure of the QCD amplitudes are studied. In dimensional regularization, the infrared pole structure is in agreement with Catani’s proposal, confirming the universal factorization property of QCD amplitudes, even with the spin-2 tensorial coupling.
