Collider production of Electroweak resonances from photon-photon states

Abstract

We estimate production cross sections for 2-body resonances of the Electroweak Symmetry Breaking sector (in $W_L{W}_L$ and $Z_L{Z}_L$ rescattering) from $\gamma \gamma$ scattering. We employ unitarized Higgs Effective Field Theory amplitudes previously computed coupling the two photon channel to the EWSBS. We work in the Effective Photon Approximation and examine both $e^{-}{e}^{+}$ collisions at energies of order 1-2 TeV (as relevant for future lepton machines) and $pp$ collisions at LHC energies. Dynamically generating a spin-0 resonance around 1.5 TeV (by appropriately choosing the parameters of the effective theory) we find that the differential cross section per unit $s$, $p_t^2$ is of order 0.01 fbarn/TeV${}^4$ at the LHC. Injecting a spin-2 resonance around 2 TeV we find an additional factor 100 suppression for $p_t$ up to 200 GeV. The very small cross sections put these $\gamma \gamma$ processes, though very clean, out of reach of immediate future searches.
