Description
Despite the discovery of the Higgs boson decay in five separate channels many parameters of the Higgs boson remain largely unconstrained. 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 and measuring the visible and partially visible Higgs boson cross section. This approach complements existing approaches from the off-shell technique and lepton colliders. To measure the Higgs boson decays, we rely on new ideas from machine learning for jet classification and a modified jet reconstruction that uses a dedicated missing energy regression. With some assumptions, this approach is found to be capable of yielding similar sensitivity to the off-shell projections with the full High Luminosity-LHC dataset. We outline the theoretical and experimental limitations of this approach and present a path towards making a truly model-independent measurement of the Higgs boson total width.
