Case studies

• Measurement of the ZH production cross section with hadronic Z decays (and the Higgs self-coupling): hadronic mass and hadronic recoil-mass resolutions
• The Higgs coupling to charm quarks (and bottom quarks, and gluons): flavour tagging, vertexing (hence beam-pipe radius, tracker material etc)
• Determination of the HZγ effective coupling: photon identification, energy and angular scale
• The invisible Higgs branching fraction: hadronic mass resolution, hadronic recoil-mass resolutions, maybe b-tagging performance
• The total decay width of the Higgs boson via ZZZ* events: jet clustering algorithms, jet directions, kinematic fits (separation of H → ZZ∗ and H → WW∗ )
• The total decay width of the Higgs boson via bbnunu events: visible and missing mass resolutions
• The Higgs boson mass and σ(ZH) from the recoil mass with leptonic Z decays: lepton momentum resolution
• The Higgs boson mass from ZH -> bbqq: jet angular resolution, b-tagging
• Electron Yukawa coupling via s-channel e+e− → H production at the Higgs pole: monochromatization
