Towards Measuring the Higgs Boson Self-coupling
#IEAP
The prediction of a Higgs boson self-coupling HHH is fundamental to the Higgs boson mechanism. The experimental observation has been a long-term challenge in particle physics owing to the small expected production cross-section of about 33 fb compared to a cross-section of about 70 fb for single Higgs boson production tH, 507 fb production cross-section for ttH, and a total Higgs boson production cross-section of about 50 pb. The expected di-Higgs boson production leads to a large number of final states as both Higgs bosons decay independently into heavy quarks, tau-leptons and gauge bosons. The IEAP contribution is in the final states with light leptons and hadronically decaying taus.
