leading jets is required to be greater than 60. The jet energy scale uncertainty for these corrected jets is 5% [@JES]. The $\ETmiss$ is defined as the negative of the vector sum of the transverse energies () of all the particles found by the particle-flow algorithm [@PFMET].

Electrons are reconstructed using a combination of shower shape information and matching between tracks and electromagnetic clusters [@CMS_e]. Muons are reconstructed using information from the muon detectors and the silicon tracker and are required to be consistent with the reconstructed primary vertex [@CMS_mu].

The selection criteria for electrons and muons are considered to be [*tight*]{} if the electron or muon candidate is isolated, satisfies the selection requirements of Ref. [@CMS_WZ], and lies within $\abs{\eta}<2.5$ and $\abs{\eta}<2.1$, respectively. [*Loose*]{} electron and muon candidates satisfy relaxed isolation requirements.

Selection of good quality data
------------------------------

The 4.7integrated luminosity used in this analysis is certified as having a fully functional detector. Events with various sources of noise in the ECAL or HCAL detectors are rejected using either topological information, such as unphysical charge sharing between neighboring channels, or timing and pulse shape information. The last requirement exploits the difference between the shapes of the pulses that develop
