Abstract

Chapters 47 describe the details of the \(H \rightarrow WW\)analysis: the selection of signal events and the rejection of backgrounds, and how each process is modelled. By comparing the expected and observed events passing the selection criteria, with a careful treatment of statistical and systematic uncertainties, it is possible to make statistically meaningful statements about the \(H \rightarrow WW\)process, based upon the Run I dataset.

Notes

  1. 1.

    This analysis is optimised to search for a low-mass Higgs boson and therefore the region \(m_{H}> 200\) GeV is not considered. A dedicated high-mass search for \(H \rightarrow WW\) is described in reference [8].
