Description
An important aspect of the Higgs boson is its width–the quantity related to its lifetime and energy spectrum. Methods for measuring the Higgs boson total decay width from the off-shell to on-shell signal strength ratio will be presented for the decays of H→WW→2l2ν, H→ZZ→2l2ν, and H→ZZ→4l.
Measurement of the Higgs boson width from the on-shell peak using the H->γγ final state will be presented using the Run2 data collected by the CMS experiment. The Higgs width is constrained using CMS data collected between 2016 and 2018, corresponding to a total integrated luminosity of 138 fb−1.
