Higgs pair production in the composite Higgs model

Abstract

In composite Higgs models the Higgs boson arises as a pseudo Nambu-Goldstone boson of an enlarged global symmetry. The Higgs potential is generated by loops of Standard Model fermions and gauge bosons. To reconstruct the Higgs potential trilinear and quartic couplings must be measured. In the composite Higgs model these couplings are modified compared to the SM and they depend on a new parameter ‐ the compositeness parameter ξ . In this talk the Higgs pair production cross sections in two composite Higgs models will be represented. The prospects of extracting the triple Higgs coupling will be discussed.
