---+!! Z'&#8594; W<sup>+</sup>W<sup>-</sup>&#8594;l<sup>±</sup>jjMET Analysis

---++ Two Z' Models

Below we see two curves describing the Z' total width versus Z' mass. We did these curves using the "Extended Gauge Model" and the "Reference Model":

And in the framework of the "Extended Gauge Model" we see the branching ratios for Z' transitions to leptons, quarks and W bosons:

---++ Some Distributions at Generator Level (Extended Gauge Model)

Here I show some distributions making a kind of validation and also looking for possibles interesting variables to do the Z' analysis in the channel: l<sup>±</sup>jjMET. First we see some distributions for a specific Z' mass (M<sub>Z'</sub> = 1 TeV) and after I present distributions looking for the behavior of some variables when we vary Z' mass.
   
   * Transversal momentum distributions of the leptons from W decay (M<sub>Z'</sub> = 1 TeV):

   * We divided the two quarks from W&#8594;qq'bar in "quark lead" (highest pT) and "quark next" (smallest pT). Below we show these distributions (M<sub>Z'</sub> = 1 TeV):

   * We studied also the variable dR, distance in etaXphi plane, for leptons and quarks (M<sub>Z'</sub> = 1 TeV):

<center> <img src="/twiki/bin/viewfile/Main/ZprimeToWWToljjMETAnalysis?rev=1;filename=ZprimeM1TeV_WW_lnu_dR.png" width=350 > <img src="/twiki/bin/viewfile/Main/ZprimeToWWToljjMETAnalysis?rev=1;filename=ZprimeM1TeV_WW_qqbar_dR.png" width=350 > <img src="/twiki/bin/viewfile/Main/ZprimeToWWToljjMETAnalysis?rev=1;filename=ZprimeM1TeV_WW_QQbarNuLep_dR.png" width=350/> </center>

   * When the W decays in an electron plus a neutrino, it's possible that this electron decays in a photon plus another electron. We studied the momentum and the angular distance between this last electron (electron2) and the photon (M<sub>Z'</sub> = 1 TeV):

<center> <img src="/twiki/bin/viewfile/Main/ZprimeToWWToljjMETAnalysis?rev=1;filename=ZprimeM1TeV_WW_Ele2Gamma_pt.png" width=350 > <img src="/twiki/bin/viewfile/Main/ZprimeToWWToljjMETAnalysis?rev=1;filename=ZprimeM1TeV_Ele2Photon_dphi.png" width=350 > <img src="/twiki/bin/viewfile/Main/ZprimeToWWToljjMETAnalysis?rev=1;filename=ZprimeM1TeV_Ele2Photon_dR.png" width=350/> </center>

   * Now we present the WW invariant mass and the Z' p<sub>T</sub> for M<sub>Z'</sub> = 0.5, 1.0, 1.5 and 2.0 TeV:

<center> <img src="/twiki/bin/viewfile/Main/ZprimeToWWToljjMETAnalysis?rev=1;filename=Zprime_WW_InvMass.png" width=350 > <img src="/twiki/bin/viewfile/Main/ZprimeToWWToljjMETAnalysis?rev=1;filename=Zprime_pT.png" width=350/> </center>

   * Leptons (electrons and muons) p<sub>T</sub> and MET (neutrinos p<sub>T</sub>) for M<sub>Z'</sub> = 0.5, 1.0, 1.5 and 2.0 TeV:

<center> <img src="/twiki/bin/viewfile/Main/ZprimeToWWToljjMETAnalysis?rev=1;filename=Zprime_lepPT.png" width=350 > <img src="/twiki/bin/viewfile/Main/ZprimeToWWToljjMETAnalysis?rev=1;filename=Zprime_MET.png" width=350/> </center>

   * "Quark lead" and "quark next" p<sub>T</sub> for M<sub>Z'</sub> = 0.5, 1.0, 1.5 and 2.0 TeV:

<center> <img src="/twiki/bin/viewfile/Main/ZprimeToWWToljjMETAnalysis?rev=1;filename=Zprime_qLeadPT.png" width=350 > <img src="/twiki/bin/viewfile/Main/ZprimeToWWToljjMETAnalysis?rev=1;filename=Zprime_qNextPT.png" width=350/> </center>

   * Distance in etaXphi plane (dR) between lepton and neutrino (quark and anti-quark) for M<sub>Z'</sub> = 0.5, 1.0, 1.5 and 2.0 TeV:

<center> <img src="/twiki/bin/viewfile/Main/ZprimeToWWToljjMETAnalysis?rev=1;filename=Zprime_LepNu_dR.png" width=350 > <img src="/twiki/bin/viewfile/Main/ZprimeToWWToljjMETAnalysis?rev=1;filename=Zprime_qqbar_dR.png" width=350/> </center>
