# Coupling WW, ZZ unitarized amplitudes to $$\gamma \gamma $$γγ in the TeV region

@article{Delgado2016CouplingWZ, title={Coupling WW, ZZ unitarized amplitudes to \$\$\gamma \gamma \$\$$\gamma$$\gamma$ in the TeV region}, author={Rafael L. Delgado and Antonio Dobado and Felipe J. Llanes-Estrada}, journal={The European Physical Journal C}, year={2016}, volume={77}, pages={1-13} }

We define and calculate helicity partial-wave amplitudes for processes linking the Electroweak Symmetry Breaking Sector (EWSBS) to $$\gamma \gamma $$γγ, employing (to NLO) the Higgs-EFT (HEFT) extension of the Standard Model and the Equivalence Theorem, while neglecting all particle masses. The resulting amplitudes can be useful in the energy regime ($$500~\mathrm{{GeV}}{-}3~\mathrm{{TeV}}$$500GeV-3TeV). We also deal with their unitarization so that resonances of the EWSBS can simultaneously be…
