title: "Table 1" of "Search For Higgs Boson Pair Production in the $\gamma\gamma b\bar{b}$ Final State using $pp$ Collision Data at $\sqrt{s}=8$ TeV from the ATLAS Detector"

description: The observed and expected limit on non-resonant Higgs boson pair production, measured in the GAMMA GAMMA B BBAR final state.
description: CERN-LHC. Searches are performed for resonant and non-resonant Higgs boson pair production in the hh to gamma gamma b bbar final state using 20/fb of proton--proton collisions at a center-of-mass energy of 8 TeV recorded with the ATLAS detector at the CERN Large Hadron Collider. A 95% confidence level upper limit on the cross section times branching ratio of non-resonant production is set at 2.2 pb, while the expected limit is 1.0 pb. The corresponding limit observed for a narrow resonance ranges between 0.7 and 3.5 pb as a function of its mass.

UPDATE (23 NOV 2014): corrected error in the limit setting that (dramatically) affects the uncertainties on the expected limits.

title: "Table 1" of "Measurement of D* photoproduction at three different centre-of-mass energies at HERA"

description: The cross sections for the production of D*+- mesons normalised to the HER data sample.
description: DESY-HERA. The cross sections for the photoproduction of D* mesons have been measured with the ZEUS detector at HERA at three different E P centre-of-mass energies, sqrt(s), of 318, 251 and 225 GeV. The data were collected in 2006 and 2007. For each data set, D* mesons were required to have transverse momentum, PT(D*), and pseudorapidity, ETARAP(D*), in the ranges 1.9 &lt; PT(D*) &lt; 20 GeV and ABS(ETARAP(D*)) &lt; 1.6. The events were required to have a virtuality of the incoming photon, Q**2, of less than 1 GeV**2. 

The data samples at sqrt(s) = 318, 251 and 225 GeV are referred to, respectively, as the high- (HER), medium- (MER) and low-energy-running (LER) samples. The corresponding luminosities of the HER, MER and LER samples are 144, 6.3 and 13.4 pb^{-1} , respectively. The dependence of the cross sections on sqrt(s) was studied by normalising to the HER sample. This led to the cancellation of a number of systematic effects both in data and theory. The normalised cross section is given by R(SIG) = SIG/SIG(HER).

title: "Table 1" of "Evidence for Electroweak Production of $W^{\pm}W^{\pm}jj$ in $pp$ Collisions at $\sqrt{s}=8$ TeV with the ATLAS Detector"

description: The fiducial cross sections for the production of W+- W+- JET JET in the inclusive and VBS regions.
description: CERN-LHC. We present the first study of W+- W+- JET JET, same-electric-charge diboson production in association with two jets, using 20.3 fb^{-1} of proton-proton collision data at sqrt(s) = 8 TeV recorded by the ATLAS detector at the Large Hadron Collider. Events with two reconstructed same-charge leptons (E+- E+-, E+- MU+-, and MU+- MU+-) and two or more jets are analyzed. Production cross sections are measured in two fiducial regions, with different sensitivities to the electroweak and strong production mechanisms. First evidence for W+- W+- JET JET production and electroweak-only W+- W+- JET JET production is observed with a significance of 4.5 and 3.6 standard deviations respectively. 

The first region or "inclusive region" is defined to study the combination of electroweak and strong production mechanisms, and in this region both processes are referred to as signal. It is defined at particle level as follows. Exactly two prompt charged leptons (tau leptons and leptons originating from tau decays are excluded) are required with the same electric charge, transverse momentum PT &gt; 25 GeV, ABS(ETA) &lt; 2.5, invariant mass M &gt; 20 GeV, and angular separation DELTA(R) = SQRT( DELTA(PHI)**2 + DELTA(ETA)**2 ) &gt; 0.3. At least two jets reconstructed with the anti-kt algorithm with jet size R = 0.4 and with PT &gt; 30 GeV, ABS(ETA) &lt; 4.5, and separated from the leptons by DELTA(R(LEPTON JET)) &gt; 0.3 are also required. The invariant mass of the two jets with the largest PT must be larger than 500 GeV, and the magnitude of the missing transverse momentum reconstructed using all neutrinos in the final state must be greater than 40 GeV. To reduce the dependence on QED radiation, lepton momenta include contributions from photons within DELTA(R) = 0.1 of the lepton direction. 

The second region or "VBS region" is a subset of the inclusive region that also requires the two jets with largest PT to be separated in rapidity by DELTA(Y(JET JET)) &gt; 2.4. This enhances the purity of electroweak W+- W+- JET JET by removing most of the strong W+- W+- JET JET events, which are considered as a background in this region.

description: CERN-LHC. The differential cross section for the process Z/gamma*-&gt;ll (l=e,mu) as a function of dilepton invariant mass is measured in pp collisions at sqrt(s) = 7 TeV at the LHC using the ATLAS detector. The measurement is performed in the e and mu channels for invariant masses between 26 GeV and 66 GeV using an integrated luminosity of 1.6 fb^-1 collected in 2011 and these measurements are combined. The analysis is extended to invariant masses as low as 12 GeV in the muon channel using 35 pb^-1 of data collected in 2010. The cross sections are determined within fiducial acceptance regions and corrections to extrapolate the measurements to the full kinematic range are provided. Next-to-next-to-leading-order QCD predictions provide a significantly better description of the results than next-to-leading-order QCD calculations, unless the latter are matched to a parton shower calculation.

title: "Table 2" of "Measurement of the low-mass Drell-Yan differential cross section at sqrt(s)=7 TeV using the ATLAS detector"

description: The systematic uncertainties of the nominal electron-channel cross-section measurement. Some sources of uncertainty have both correlated and uncorrelated components. Correlated uncertainties arise from the uncertainty in the electroweak background contributions delta(e.w.)_cor, from corrections to the Monte Carlo modelling of the Z/gamma* pT spectra, delta(pTrw)_cor, the electron identification efficiency, delta(id)_cor1 and delta(id)_cor2, the reconstruction efficiency, delta(rec)_cor, and from the Geant4 simulation, delta(geant4)_cor. Uncorrelated uncertainties arise from the isolation and trigger efficiency corrections, delta(trig) and delta(iso) respectively, unfolding uncertainties, delta(res)_unf, and the statistical precision of the signal Monte Carlo, delta(MC). The electron identification efficiency uncertainties have several components other than the two largest correlated parts above. These additional components are all combined into a single uncorrelated error source delta(id)_unc. The uncertainty on the normalisation of the multijet background is given by delta(multijet). The luminosity uncertainty 1.8% is not included.
