## Plots from Rivet analyses

### W+jets production at 7 TeV (ATLAS_2012_I1083318)

Spires | arXiv:1201.1276 [hep-ex]

Differential cross-sections of properties of the four leading jets in $W$+jets production, using the full 2010 dataset of 36 pb$^-1$. Observables include jet multiplicities, $pT$, $H_T$, angular distances, and others. All observables are available using jets with $pT>30$ and $pT>20$ GeV.

### Measurement of the Z pT with electrons and muons at 7 TeV (ATLAS_2011_S9131140)

Spires | arXiv:1107.2381 [hep-ex]

The Z pT at $\sqrt{s} = 7$\;TeV is measured using electron and muon $Z$ decay channels. The dressed leptons definition uses photons clustered in a cone around the charged leptons, while the bare lepton definition uses the post-FSR charged leptons only in the $Z$ reconstruction. The data used in the bare leptons calculation are based on a forward application of a PHOTOS-based energy loss correction and are hence not quite model-independent.

### Muon charge asymmetry in W events at 7 TeV in ATLAS (ATLAS_2011_S9002537)

Spires | arXiv:1103.2929

Measurement of the muon charge asymmetry from W bosons produced in proton-proton collisions at a centre-of-mass energy of 7 TeV with ATLAS. The asymmetry is measured in the $W \rightarrow \mu$ decay mode as a function of the muon pseudorapidity using a data sample corresponding to a total integrated luminosity of 31pb$^-1$.

### Measurement of the W pT with electrons and muons at 7 TeV (ATLAS_2011_I925932)

Spires | arXiv:1108.6308v1 [hep-ex]

The W pT at $\sqrt{s} = 7$\;TeV is measured using $W\to e \, \nu_e$ and $W\to \mu \, \nu_\mu$ decay channels. The dressed leptons kinematics calculated from the sum of the post-FSR lepton momentum and the momenta of all photons radiated in a cone around the lepton, while the bare uses the lepton kinematics after all QED radiation.

### W+jets jet multiplicities and pT (ATLAS_2010_S8919674)

Spires | arXiv:1012.5382 [hep-ex]

Cross sections, in both the electron and muon decay modes of the W boson, are presented as a function of jet multiplicity and of the transverse momentum of the leading and next-to-leading jets in the event. Measurements are also presented of the ratio of cross sections for inclusive jet multiplicities. The results, based on an integrated luminosity of 1.3 pb-1, have been corrected for all known detector effects and are quoted in a limited and well-defined range of jet and lepton kinematics.

### Monte Carlo validation observables for $Z[e^+ \, e^-]Z[\mu^+ \, \mu^-]$ + jets production (MC_ZZJETS)

In addition to the typical jet observables this analysis contains observables related to properties of the ZZ-pair momentum, correlations between the ZZ, properties of the Z bosons, properties of the leptons, correlations between the opposite charge leptons and correlations with jets.

### Monte Carlo validation observables for $Z[e^+ \, e^-]$ + jets production (MC_ZJETS)

Available observables are Z mass, pT of jets 1-4, jet multiplicity, $\Delta\eta(Z, \text{jet1})$, $\Delta R(\text{jet2}, \text{jet3})$, differential jet rates 0->1, 1->2, 2->3, 3->4, integrated 0--4 jet rates.

### Monte Carlo validation observables for $W^+[e^+ \, \nu]W^-[\mu^- \, \nu]$ + jets production (MC_WWJETS)

In addition to the typical jet observables this analysis contains observables related to properties of the WW-pair momentum, correlations between the WW, properties of the W bosons, properties of the leptons, correlations between the opposite charge leptons and correlations with jets.

### Monte Carlo validation observables for $W$ polarisation (MC_WPOL)

Observables sensitive to the polarisation of the W boson: A0, ... A7, fR, fL, f0, separately for W+ and W-.

### Monte Carlo validation observables for $W[e \, \nu]$ + jets production (MC_WJETS)

Available observables are W mass, pT of jets 1-4, jet multiplicity, $\Delta\eta(W, \text{jet1})$, $\Delta R(\text{jet2}, \text{jet3})$, differential jet rates 0->1, 1->2, 2->3, 3->4, integrated 0--4 jet rates.
