title: "Table 2" of "Measurement of Inclusive ep Cross Sections at High Q2 at sqrt(s) = 225 and 252 GeV and of the Longitudinal Proton Structure Function FL at HERA"

description: The neutral current reduced cross section at Q^2=45 GeV^2 for a proton energy of 460 GeV.
description: DESY-HERA. Measurements of EP double differential cross sections for neutral current DIS from collisions of leptons with energies of 27.6 GeV and protons with reduced beam energies of 460 and 575 GeV taken during 2007. The measurments cover the X region 0.00065-0.65 and Q**2 from 35-800 GeV^2 up to Y=0.85. 

These new measurments are combined with previously published H1 data at Ep=920 GeV and lower Q^2 data at Ep=460, 575 and 920 GeV to extract the longitudinal structure function FL in the Q^2 region 1.5-800 GeV^2.

title: "Table 6" of "Measurement of ZZ production in pp collisions at sqrt(s)=7 TeV and limits on anomalous ZZZ and ZZgamma couplings with the ATLAS detector"

description: Normalized ZZ fiducial cross section (multiplied by 10^6 for readability) in bins of deltaPhi between the two leptons for the 2l2nu channel. The first systematic uncertainty is detector systematics, the second is background systematic uncertainties.
description: CERN-LHC. Measurements of the cross section for ZZ production using the 4l and 2l2nu decay channels in proton-proton collisions at a centre-of-mass energy of 7 TeV with 4.6 fb^-1 of data collected in 2011. The final states used are 4 electrons, 4 muons, 2 electrons and 2 muons, 2 electrons and missing transverse momentum, and 2 muons and missing transverse momentum (MET).

The cross section values reported in the tables should be multiplied by a factor of 1.0141 to take into account the updated value of the integrated luminosity for the ATLAS 2011 data taking period. The uncertainty on the global normalisation ("Lumi") remains at 1.8%. See Eur.Phys.J. C73 (2013) 2518 for more details.

The 4l channel fiducial region is defined as:
- 4e, 4mu or 2e2mu
- Ambiguities in pairing are resolved by choosing the combination that results in the smaller value of the sum |mll - mZ| for the two pairs, where mll is the mass of the dilepton system.
- ptLepton &gt; 7 GeV (at least one with ptLepton &gt; 20 (25) GeV for muons (electrons))
- |etaLepton| &lt; 3.16
- At least one lepton pair is required to have invariant mass between 66 and 116 GeV. If the second pair also satisfies this, the event is ZZ, otherwise if the second pair satisfies mll &gt; 20 GeV it is ZZ*.
- min(DeltaR(l,l)) &gt; 0.2.

The 2l2nu channel fiducial region is defined as:
- 2e+MET or 2mu+MET
- ptLepton &gt; 20 GeV
- |etaLepton| &lt; 2.5
- mll must be between 76 and 106 GeV
- -MET*cos(phi_METZ)&gt;75 GeV, where phi_METZ is the angle between the Z and the MET
- |MET - pTZ| / pTZ &lt; 0.4, where pTZ is the transverse momentum of the dilepton system
- No events with a jet for which ptJet &gt; 25 GeV and |etaJet| &lt; 4.5

Measurements of EP double differential cross sections for neutral current DIS from collisions of leptons with energies of 27.6 GeV and protons with reduced beam energies of 460 and 575 GeV taken during 2007. The measurments cover the X region 0.00065-0.65 and Q**2 from 35-800 GeV^2 up to Y=0.85. 

These new measurments are combined with previously published H1 data at Ep=920 GeV and lower Q^2 data at Ep=460, 575 and 920 GeV to extract the longitudinal structure function FL in the Q^2 region 1.5-800 GeV^2.
