Search for non-resonant di-Higgs production in the decay channel bbWW with two leptonically decaying W boson with the CMS experiment — Martin Erdmann, •Peter Fackeldey, Benjamin Fischer, and Dennis Noll — III. Physikalisches Institut A - RWTH Aachen University

A measurement of the di-Higgs boson production constitutes a direct test of the electroweak symmetry breaking in the standard model of particle physics (SM). The coupling strength between three Higgs bosons (self-coupling) determines the shape of the Higgs potential and thus the vacuum stability of the universe. The cross section of the di-Higgs boson production is about a factor of thousand smaller in comparison to a single SM Higgs boson, making it a highly challenging statistically search.

The expected sensitivity for the HH→bbWW(lν lν) final state is shown corresponding to Run II data.
