The data analysed correspond to an integrated luminosity of 4.6 fb⁻¹ recorded 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 determined 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. Results are compared to leading-order and next-to-leading-order perturbative QCD calculations.en-USCC BY 4.0 (Attribution)©2014 CERN, for the ATLAS Collaborationhttp://creativecommons.org/licenses/by/3.0/Jets (Nuclear physics)QuarksZ bosonsProton-proton interactionsMonte Carlo FeMtobarn (MCFM)TextAad, G., B.
