title: "Table 1" of "Measurement of differential production cross-sections for a $Z$ boson in association with $b$-jets in 7 TeV proton-proton collisions with the ATLAS detector"

description: Integrated $Z+\ge 1$ $b$-jet cross-section and the integrated inclusive $b$-jet cross-sections.
description: CERN-LHC. Measurements of differential production cross-sections of a Z boson in association with b-jets in pp collisions at sqrt(s) = 7 TeV are reported. The data analysed correspond to an integrated luminosity of 4.6 fb^{-1} recorded in 2011 with the ATLAS detector at the Large Hadron Collider. Particle-level cross-sections are determined for events with a Z boson decaying into an electron or muon pair, and containing b-jets. For events with at least one b-jet, the cross-section is presented as a function of the Z boson transverse momentum and rapidity, together with the inclusive b-jet cross-section as a function of b-jet transverse momentum, rapidity and angular separations between the b-jet and the Z boson. For events with at least two b-jets, the cross-section is deter mined as a function of the invariant mass and angular separation of the two highest transverse momentum b-jets, and as a function of the Z boson transverse momentum and rapidity.

Theoretical non-perturbative corrections for the differential cross-sections are given in the tables below as multiplicative correction factors applied to parton-level theory predictions from MCFM to account for the softening of the jet spectra due to fragmentation and hadronisation and to the enhancement of the cross-section due to multi-parton interactions (MPI). A constant QED multiplicative factor, correcting the born lepton definition in MCFM to the dressed definition used in the analysis, is included. The various sources of uncertainties (MC sample size, differences between PYTHIA and SHERPA in the modelling of NP-QCD effects, QED final state radiation (FSR) correction and uncertainties on the modelling of the double parton interaction from a comparison to data) are listed separately.
