Abstract

The following chapter describes the analysis of the electron and muon channel. First all MC samples used for the analysis are discussed in Sect. 9.1. The data used and the event and lepton selection criteria are discussed in Sect. 9.2. The determination and validation of the multijet background is discussed in Sect. 9.3 and the extrapolation of the MC and multijet background towards high transverse mass is presented in Sect. 9.4. The systematic uncertainties on the background estimation are discussed in Sect. 9.5. Finally, the selected data are compared to the Standard Model background expectation in Sect. 9.6.

Notes

  1. 1.

    The PDF4LHC prescription for calculating the PDF uncertainties is to take the envelope of the uncertainties from the MSTW2008 68% CL NNLO, CT10 NNLO and NNPDF2.3 5f FFN PDF sets.

  2. 2.

    The Good Runs List used in this analysis is: data15_13TeV.periodAllYear_DetStatus-v73-pro19-08_DQDefects-00-01-02_PHYS_StandardGRL_All_Good_25ns.xml.

  3. 3.

    e24_lhmedium_L1EM20VH or e60_lhmedium or e120_lhloose.

  4. 4.

    The isolation requires the energy in the hadronic calorimeter in \(2\times 2\) cells behind the energy deposition in the electromagnetic calorimeter to be less than \(20{\mathrm {\,GeV}}-22{\mathrm {\,GeV}}\) (depending on the region in \(\eta \)).

  5. 5.

    Tight.

  6. 6.

    Medium.

  7. 7.

    Jets can also contain neutrinos from heavy-flavor decays, but this is not expected to be the dominant background in this case.
