A method to search for the non-resonant di-Higgs production cross-section in the dileptonic HH→bbWW final state — Martin Erdmann, •Peter Fackeldey, Benjamin Fischer, and Dennis Noll — III. Physikalisches Institut A, RWTH Aachen University

The measurement of the di-Higgs boson production is 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 statistically challenging search.
The expected sensitivity for the HH→bbWW(lν lν) final state is shown corresponding to Run II data.
