Description
Despite the discovery of the Higgs boson decay in five separate channels many parameters of the Higgs boson remain unknown. One of these unknown parameters is the Higgs boson total width. Currently, the best known approach to measure the Higgs boson total width at the LHC is indirectly through Higgs interference of off-shell Z boson pair production. In this paper, we present a new approach to constraining the Higgs total width by requiring the Higgs to be resolved as a single high pT jet. We show that this approach is capable of yielding similar sensitivity to the off-shell measurement. Additionally, we outline the theoretical limitations of this and present an attempt at utilizing machine learning to minimize the theoretical assumptions. Finally, we outline the required insights needed to make this approach a truly model independent measurement of the Higgs boson total width.
