WebAnd the total width (decay rate) around 170 GeV increases exactly because the Higgs decays to the WW final states start to become possible. Because the total width goes up, the ratio of a (non-WW) partial width and the total width goes down - and this ratio is what we call the branching ratio. Kostya wrote almost the same thing. WebThe theory of these Higgs boson decays is very simple. However, by now you all know that the LHC experiments exclude a Standard Model Higgs boson in the mass range where decay to these particles would be permitted. The Higgs resonance found at the LHC has a mass of 125 GeV. Therefore, all of the actual decays of the Higgs boson are
WebThe total decay width for a light Higgs boson with a mass in the observed range is not expected to be directly observable at the LHC. For the case of the Standard Model the prediction for the total width is about 4 MeV, which is several orders of magnitude smaller than the experimental mass resolution.
