title: "Table 5" of "Study of forward Z+jet production in pp collisions at $\sqrt{s} = 7$ TeV"

description: Differential cross-section for $Z$+jet in the boson $Z$ rapidity, $y^Z$.
description: CERN-LHCb. Measurement of the $Z(\to \mu^+ \mu^-) + $jet production cross-section in $pp$ collisions at a centre-of-mass energy $\sqrt{s}=7$ TeV using an integrated luminosity of 1.0 fb$^{-1}$ recorded by the LHCb experiment. Results are shown with two jet transverse momentum thresholds, 10 and 20 GeV/$c$, for both the overall cross-section within the fiducial volume, and for six differential cross-section measurements. The fiducial volume requires that both the jet and the muons from the $Z$ boson decay are produced in the forward direction ($2.0 &lt; \eta &lt; 4.5$). A further condition is applied on the separation between each of the muons and the jet, $\Delta r=\sqrt{(\Delta\phi)^2 + (\Delta\eta)^2}$ (see DR below). The results show good agreement with theoretical predictions at the second-order expansion in the coupling of the strong interaction.

title: "Table 1" of "Measurements of the ZZ production cross sections in the 2 l 2 nu channel in proton-proton collisions at sqrt(s) = 7 and 8 TeV and combined constraints on triple gauge couplings"

description: pp-&gt;ZZ-&gt;2l2nu reduced-MET distribution in the 7 TeV dataset. Uncertainties are statistical. Last bin includes overflow events.
description: CERN-LHC. Measurements of the ZZ production cross section in proton-proton collisions at center-of-mass energies of 7 and 8 TeV are presented. 
Candidate events for the leptonic decay mode ZZ-&gt;2l2nu, where l denotes an electron or a muon, are reconstructed and selected from data corresponding to an integrated luminosity of 5.1 (19.6)/fb at 7 (8) TeV collected with the CMS experiment.
The selected data are analyzed to search for anomalous triple gauge couplings involving the ZZ final state. These limits are then combined with the previously published CMS results for ZZ in 4l final states.

We define a reduced missing transverse energy (reduced-MET) variable: 
- The transverse momenta (pT) of all the individual particle candidates in the event and of the clustered jets are decomposed along an orthogonal set of
 axes in the transverse plane of the detector. One of the axes is
 defined by the pT of the charged dilepton system (pT(ll)), the other perpendicular to it. - We define the recoil of the l+l' system in two different
ways: (1) the clustered recoil (Rc) is the vectorial sum of the
momenta of the jets reconstructed in the event (2) the unclustered recoil (Ru) is the vectorial sum of the transverse momenta of all particle candidates in
the event, with the exception of the two leptons. - On each
axis (i = parallel/orthogonal to the dilepton system pT), the reduced MET projection is defined as:
reduced-MET_i = - pT(ll)_i - Rc/u_i, where Rc/u_i
represents the choice of Rc or Ru that minimizes the absolute value
of that reduced-MET component, and pT(ll)_i is a projection of the transverse momentum of the Z boson.
- The absolute reduced-MET variable is the sum in quadrature of the two components.
Selection is defined as: - 2l (l=e+,e-,mu+,mu-). No opposite charge sign is required.
- pT(mu) &gt; 20 GeV; |eta(mu)| &lt; 2.4

- pT(ll) &gt; 45 GeV
- Events containing jets with pT &gt; 20 GeV and identified as b-quark jets are rejected

- Reduced-MET &gt; 65 GeV
- 0.4 &gt; MET/pT(ll) &gt; 1.8

- DeltaPhi(MET,lepton) &gt; 0.2 rad
