title: "Table 69" of "Search for direct third-generation squark pair production in final states with missing transverse momentum and two b-jets in sqrt{s}=8 TeV pp collisions with the ATLAS detector"

description: Total experimental systematic uncertainty in percent on the signal efficiency times acceptance in the ( M(CHARGINO), M(NEUTRALINO) ) mass plane with M(STOP) = 300 GEV for the stop pair production scenario. All the different "down" values have been added in quadrature. The best expected signal region selection is used per point.
description: CERN-LHC. The results of a search for pair production of supersymmetric partners of the Standard Model third-generation quarks are reported. This search uses 20.1 fb^-1 of pp collisions at sqrt(s) = 8 TeV collected during the period from March to December 2012 by the ATLAS experiment at the Large Hadron Collider. The lightest bottom and top squarks (b1 and t1 respectively) are searched for in a final state with large missing transverse momentum and two jets identified as originating from b-quarks. No excess of events above the expected level of Standard Model background is found. The results are used to set upper limits on the visible cross section for processes beyond the Standard Model. Exclusion limits at the 95% confidence level on the masses of the third-generation squarks are derived in phenomenological supersymmetric R-parity-conserving models in which either the bottom or the top squark is the lightest squark. The b1 is assumed to decay via b1 --&gt; b chi1^0 (where chi1^0 is the lightest neutralino) and the t1 via t1 --&gt; b chi1^{+/-} (where chi1^{+/-} is the lightest chargino), with undetectable products of the subsequent decay of the chi1^{+/-} due to the small mass splitting between the chi1^{+/-} and the chi1^0.

title: "Table 1" of "Search for Quantum Black-Hole Production in High-Invariant-Mass Lepton+Jet Final States Using Proton-Proton Collisions at sqrt(s) = 8 TeV and the ATLAS Detector"

description: The combined 95% CL upper limits on the cross section times branching fraction (SIG*BR) for Quantum Black Holes decaying to a lepton and jet, as a function of the threshold mass, Mth.
description: CERN-LHC. Search for quantum black-hole production using 20.3 inverse fb of data collected in 2012 with the ATLAS detector in pp collisions at the LHC at sqrt(s) = 8 TeV. The quantum black holes are assumed to decay into a lepton (electron or muon) and a jet. In either channel, no event with a lepton-jet invariant mass of 3.5 TeV or more is observed, consistent with the expected background. Limits are set on the product of cross sections and branching fractions for the lepton+jet final states of quantum black holes produced in a search region for invariant masses above 1 TeV. The combined 95% confidence level upper limit on this product for quantum black holes with threshold mass above 3.5 TeV is 0.18 fb. This limit constrains the threshold quantum black-hole mass to be above 5.3 TeV in the model considered.

title: "Table 2" of "Search for Quantum Black-Hole Production in High-Invariant-Mass Lepton+Jet Final States Using Proton-Proton Collisions at sqrt(s) = 8 TeV and the ATLAS Detector"

description: Numbers of observed events and expected background events for electron+jet channel, along with acceptance (A), experimental efficiency (EPSILON), cumulative efficiency (A*EPSILON), total cross section (SIG*BR) and 95% CL observed upper limit, for various values of the threshold mass, Mth. The leading order cross sections have a statistical precision of the order of 1%. The uncertainties on the predicted background include both statistical and systematic components. Acceptance is calculated using generator-level quantities by imposing selection criteria that apply directly to phase space (electron/jet eta, electron/jet pT, Delta(eta), Delta(phi), , and Minv). All other selections, which in general correspond to event and object quality criteria, are used to calculate the efficiency on the events included in the acceptance. The cumulative signal efficiency is the product of the acceptance and experimental efficiency.

title: "Table 1" of "Measurement of the production cross section of prompt J/psi mesons in association with a W boson in pp collisions at sqrt{s}=7 TeV with the ATLAS detector"

description: The W + prompt J/psi to inclusive W production cross-section ratio (times 10^6) in the J/psi fiducial region (Fiducial), after correction for J/psi acceptance (Inclusive), and after subtraction of the double parton scattering component (DPS-subtracted). The first uncertainty is statistical, the second is systematic, and the third/fourth (where applicable) is the uncertainty up/down due to spin-alignment.
description: CERN-LHC. The process P P --&gt; W J/PSI X provides a powerful probe of the production mechanism of charmonium in hadronic collisions, and is also sensitive to multiple parton interactions in the colliding protons.

A yield of 27.4 +7.5,-6.5 W + prompt J/psi events is observed, with a statistical significance of 5.1 sigma. The production rate as a ratio to the inclusive W boson production rate is measured, and the double parton scattering contribution to the cross section is estimated.

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.

title: "Table 1" 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=35 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.
