  We estimate production cross sections for 2-body resonances of the
Electroweak Symmetry Breaking sector (in $W_LW_L$ and $Z_LZ_L$ 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.
