  • Abstract We argue that the current experimental data in conjunction with perturbative unitarity considerations exclude the possibility that the LHC 125–126 GeV resonance is a generic massive spin-2 particle of either parity. We analyse tree-level Z–spin-2 elastic scattering and demonstrate that perturbative unitarity breaks down at energies Λ ∼ 600 GeV . Furthermore, we find that W , Z –spin-2 interactions contribute to the electroweak oblique parameters in a way that is in gross disagreement… CONTINUE READING
