We considered spin-two gauge boson production in the fermion pair annihilation process and calculated the polarized cross-sections for each set of helicity orientations of initial and final particles. Adding up all sixteen amplitudes and averaging over the initial particle spins, we obtained the unpolarized cross-section. The angular dependence of these cross-sections is compared with the similar annihilation cross-sections in QED with two photons in the final state, with two gluons in QCD and W-pair in the electroweak theory.
