Search for non-resonant Higgs boson pair production in the bbWW final state with leptonic W boson decays at the CMS experiment — Martin Erdmann, •Peter Fackeldey, Benjamin Fischer, and Dennis Noll — III. Physikalisches Institut A, RWTH Aachen University
The measurement of the Higgs boson pair production is a direct test of the electroweak symmetry breaking in the standard model of particle physics (SM) with direct access to the shape of the Higgs potential.
The cross section of the Higgs boson pair production is about a factor of a thousand smaller than that of a single SM Higgs boson, making it a highly challenging search. Physics-inspired deep learning techniques are leveraged for the signal extraction and the control over overwhelming backgrounds, mainly from the top pair production and Drell-Yan processes.
The expected sensitivity of the search for HH → bbWlepWlep is presented for the data-taking periods 2016, 2017, and 2018 of the CMS experiment.
