Notes

  1. 1.

    Prompt particles are defined as particles with a mean lifetime of greater than \(3\times 10^{-11}\) s directly produced in a pp interaction or from the subsequent decays or interactions of particles with a lifetime shorter than \(3\times 10^{-11}\) s.

  2. 2.

    The shower is expected to be broader in \(\phi \) due to the radiated photons from Bremsstrahlung, which are measured nearby in \(\phi \) to the electron cluster.

  3. 3.

    ElectronPhotonFourMomentumCorrection-00-01-46 has been used for the analysis described in part III and ElectronPhotonFourMomentumCorrection-00-00-34 for the analysis described in part IV.

  4. 4.

    ElectronEfficiencyCorrection-00-01-42 has been used for the analysis described in part III and ElectronEfficiencyCorrection-00-00-50 for the analysis described in part IV.

  5. 5.

    Muons deposit an energy of about \(3{\mathrm {\ GeV}}\) when traversing the calorimeter. The deposited energy is independent of the muon momentum.

  6. 6.

    JetCalibTools-00-04-61 has been used for the analysis presented in part III.

  7. 7.

    In case of the hadronically decaying \(\tau \)-leptons only the hadronic jet is calibrated and no correction is applied for the momentum carried away by the neutrino.
