MissingET Revertexing

Plots of the Revertexed MET
in postscript format, from a W -> mu + nu sample.

  • MissingET of this W -> mu nu sample
    MissingET of the sample, calculated about the event vertex.

  • Summed ring energies in this W -> mu nu sample
    Ring energies for this sample, summed for each event.

  • Z vertex for this W -> mu nu sample
    Event vertex for this sample, in cm along the Z axis.

  • MissingET and summed ring energies
    MissingET superimposed on the unvertexed ring energies.

  • Revertexed MET and summed ring energies
    Revertexed MET superimposed on the unvertexed ring energies. Revertexed using the average EM height and the average HAD height. Electromagnetic and Hadronic energies separate.

  • MET and revertexed MET
    Electromagnetic and Hadronic energies separate. Revertexed using the average EM height and the average HAD height.

  • MET and revertexed MET
    Electromagnetic and Hadronic energies separate. Revertexed using the average EM height and the average HAD height. Calorimeter energies were combined in pairs before revertexing.

  • MET minus revertexed MET, normalized by MET
    Electromagnetic and Hadronic energies separate. Revertexed using the average EM height and the average HAD height. Calorimeter energies were combined in pairs before revertexing.

  • MET minus revertexed MET, normalized by MET
    Electromagnetic and Hadronic energies separate. Revertexed using the average EM height and the average HAD height. Calorimeter energies were combined in pairs before revertexing. The revertexed MET using separate rings is superimposed in green on the plot.

  • MET and revertexed MET
    Electromagnetic and Hadronic energies separate. Revertexed using the average EM height and the average HAD height. Calorimeter energies were combined in groups of five before revertexing. The revertexed MET, in purple, is superimposed over the event MET.

  • MET minus revertexed MET, normalized by MET
    Electromagnetic and Hadronic energies separate. Revertexed using the average EM height and the average HAD height. Calorimeter energies were combined in groups of five before revertexing.

  • MET minus revertexed MET, normalized by MET
    Electromagnetic and Hadronic energies separate. Revertexed using the average EM height and the average HAD height. Calorimeter energies were combined in groups of five before revertexing. The revertexed MET using separate rings is superimposed in green on the plot.

  • MET and revertexed MET
    Electromagnetic and Hadronic energies separate. Revertexed using the average EM height and the average HAD height. Calorimeter energies were combined in groups of ten before revertexing. The revertexed MET, in purple, is superimposed over the event MET.

  • MET minus revertexed MET, normalized by MET
    Electromagnetic and Hadronic energies separate. Revertexed using the average EM height and the average HAD height. Calorimeter energies were combined in groups of ten before revertexing.

  • MET minus revertexed MET, normalized by MET
    Electromagnetic and Hadronic energies separate. Revertexed using the average EM height and the average HAD height. Calorimeter energies were combined in groups of ten before revertexing. The revertexed MET using separate rings is superimposed in green on the plot.

  • MET - ring energy, versus MET
    A scatter plot of the difference between MissingET and summed ring energies, versus the MissingET.

  • MET - revertexed MET, versus MET
    A scatter plot of the difference between MissingET and revertexed MET, versus the MissingET.

  • Profile plot of MET - revertexed MET, versus MET
    A profile histogram of the difference between MissingET and revertexed MET, normalized by the MET, versus the MissingET.

  • Profile plot of (MET - revertexed MET)/MET, versus MET
    A profile histogram of the difference between MissingET and revertexed MET, versus the MissingET.
