Description
Higgs pair production is not only interesting as a probe of the trilinear Higgs self-coupling but it can also help to constrain SM extensions. In this talk I will discuss the question whether New Physics might show up for the first time in Higgs pair production focusing on the gluon fusion production process. There is a plethora of New Physics phenomenology like new couplings, new loop particles or new resonances, that can show up in this process. Finally, I will comment on next-to leading order QCD corrections to Higgs pair production in the MSSM and in composite Higgs models with and without new vector-like fermions.
