Double Higgs production and quadratic divergence cancellation in little Higgs models with T-parity

We analyze double Higgs boson production at the Large Hadron Collider in
the context of Little Higgs models. In double Higgs production, the diagrams involved
are directly related to those that cause the cancellation of the quadratic divergence of the
Higgs self-energy, providing a robust prediction for this class of models. We find that in
extensions of this model with the inclusion of a so-called T-parity, there is a significant
enhancement in the cross sections as compared to the Standard Model.
