Study of gamma gamma -> WL WL and gamma gamma -> ZL ZL reactions with Chiral Lagrangians
Abstract
We analyze the effects of a strongly interacting symmetry breaking sector of the Standard Model in γ γ -> WL+ WL- and γ γ -> ZL ZL reactions at TeV energies by using Chiral Lagrangians and Chiral Perturbation Theory. We find significant deviations from the Standard Model predictions for the differential cross sections at high invariant mass of the gauge bosons pair. We study the experimental signals that could be obtained in a high energy and high luminosity dedicated γγ collider and estimate the sensitivity that such experiments could reach to the values of the effective lagrangian parameters.
