Expérimental et théorique Description
The trilinear Higgs boson self-coupling is of paramount importance in Higgs boson physics and its measurementn one of the major goal of the future HL-LHC at CERN. While its value is fully determined in the standard model of particle physics once the Higgs boson mass is known, it determines the peculiar shape of the Higgs potential which is at the heart of the electroweak symmetry breaking mechanism. The trilinear Higgs boson self-coupling can be measured at the LHC through the double Higgs boson production. The goal of this internship is to conduct a phenomenological study of the kinematics of this process to separate the signal amplitude from the background amplitude arising from the double Higgs production from top and bottom quark couplings, to ultimately improve the sensitivity to this measurement from double Higgs boson production.
